Motorola T605 BT Car kit

Just got the the Motorola T 605 Automotive Music and Hands-free System installed into my car. Works great with the Kaiser (I have the TILT) for both Hands-free and Wireless Stereo BT profiles. When connected with a vehicle specific adapter harness, the stereo is automatically muted for incoming calls, and conversation is played from front speakers only. A long press on the talk button even launches Cyberon Voice Speed Dial (which is provided with the TILT). When using Wireless Stereo and WMP, all skip/ forward/ back/ pause/ play functions work flawlessly. Provided BT is enabled on the kaiser before the ignition is turned on, the connection for both profiles is automatic. Very nice adition for those of us who own a car that did not come with factory BT.

Hi,
I happen to have the same car kit and my Kaiser doesn't find it!
My T605 is discovered and works flawlessly with my SonyEricsson K800i phone (both for call and streaming music) as well as my old HP IPAQ 5555 (obviously, only for music with this one).
On the other hand, my Kaiser works flawlessly with both Plantronics 590A and Jabra BT8010 in both modes.
So, what could be wrong? I have the latest Shap's ROM (4.31) on my Kaiser, didn't try it with the stock one.
Any help is much appreciated!
Thanks!

That's a tough one. Mine connected first time to both BT profiles with the 605. I do recall a limitation on the 605 regarding how many partnerships the T605 supports. Although it's a pain, I'd suggest clearing all partnerships from the T605, and the Kaiser, and then try and connect again. I'm using a TILT, but had no issues with either ROM in my sig.

Which is better? The T605 or the T505?

I think 605 requires professional install, but 505 doesn't

So I'm going to help my buddy install the T605 into his saturn Ion (04). The demo on the motorola website says you can buy a harness to make the phone call go through the oem speakers and not have to use the 5W powered speaker. Is this harness necessary or will this happen for you when you follow the install instruction?
Also, If this is not controlled by the aux port on the HU how will the music (A2DP) play through the system? There must be relays in the HF unit to do this? Or will I need to go through the aux port on the HU?
I have the IHF1000 in my car and that was a very easy install......Other than tapping into the OEM wires this should be pretty cut and dry? As long as you know what OEM wires to use?
Motorola has been completely useless as far as tech support goes.

For Motorola T605 and IHF1000 vehicle-specific adapter harnesses, try the selection from www.peripheralelectronics.com (their CelFi harnesses), or the drive&talk harnesses at www.nicestuffonline.com . A solution should be there somwhere between them for the ION.
As for the integration, connect the RCA L/R output from the T605 to an available MP3 or aux. input, or find an aux. input adapter for your vehicle (examples are from Blitzsafe, Periperhal Electronic's Aux2Car and others). If there is no specific adapter available for your vehicle, you could always use Scosche's FM-MOD01 FM modulator to bring the audio in DIRECTLY through the FM antenna port (vehicle-specific antenna adapters may be required). The in-line modulator works without static, unlike that of many FM broadcast/transmitter solutions.

As mentioned above, the easiest thing to do is start by sourcing the vehicle specific adapter from one of those companies in the previous post and go from there. I did that, and installed the t605 in my car in NO time. You just plug the adapter into the back of your stereo, plug the harness from the t605 to that, and then run the lines out for the mic and for the controls, then run RCA from the t605 to your AUX connection (either 3rd party aux interface or factory opening if you have it). It's freaking great. You're done in NO time. The handsfree is GREAT, and even better is that you can stream whatever you want from your phone... I'll take shoutcast and internet radio over paying for XM/Sirius any day of the week.

If you were able to run another moto unit you'll have no trouble with this... it just adds one connection for the audio.

I'm sure the answer is probably yes, but it helps clear things up for me to speak them out loud.
Here is what I want to have happen. I want to be able to put my Tilt in my car and have my car to play music from the Tilt through the car's speakers. I don't care whether it is through a wired connection or a wireless connection via Bluetooth or an FM transmitter. Will this do this fine?
Like I said, I think the answer is yes, but I would like someone else to confirm it. And I was going to get a separate Bluetooth headset to use in the car and just walking around. I'll still get that, but I think this should be fine when I'm driving in the car and I must take a call.
Final question. How is the sound quality coming through the speakers and how is the reception on the other end? Can they hear you fine?

It will work, but I think it's a bit overkill if you're looking to go that simple. If you're not hung up on BT why not just buy a basic AUX interface for your car with a 3.5mm jack on it, then grab the adapter to plug it into the bottom to the tilt? It's not as "cool" or "elegant" but heck, if you jsut want to play audio but don't want to stream it why make things hard?

For audio or phone calls?
It's great for audio.
Phone calls are good. Nobody every says they can't hear me, but sometimes if I'm at WOT or have the windows down I can't hear them because the volume output is a tad low. I have a loud car though, so that's more my fault than motorolas.

Wiring Harness
Hi...I have a 2007 Mazda6 with the factory Bose stereo system. I am looking for a 3rd party wiring harness so I can connect the Motorola T605 to the stereo. I have looked at the places mentioned in previous posts to find the harness, but have not been successful...this may be because I am not sure what I am looking for. If someone has any information I would be greatly appreciative...
Thanks!

How to wire stock microphone into head unit?

Hi guys, I recently got a dasaita px5 head unit and would like to make my install a bit cleaner and perhaps the audio during phone calls a bit nicer.
Now, my car is a Hyundai Solaris (Accent, but for the Russian market) and here's the pinout for the connectors
http://www.tehnomagazin.com/images/...o wiring diagram harness pinout connector.gif
Now, the external microphone that comes with the unit uses a two-pole connector like this:
http://media.rs-online.com/t_large/F6287095-01.jpg
So, should i take mic+ to be the 1 channel and mic- to be the ground bit from a mono connector? Or is my stock microphone a stereo (noise cancelling?) mic?

This would be easier to hook up... Going to order this since it can be recharged via USB.

How would you use this for the OPs original question, as this is a line in to headphone amp, the levels are much different.
OP - do you have details such as wiring diagrams for the factory mic? My toyota has an internal mic which requires 5v to power its preamp.

Weird, my original post did not show... let me start over.
So I wanted to do the same in my car (2015 Audi A3), use the stock microphone but still have it available for the built in OEM phone and voice activation features.. Basically you will have to solder or tap into the lead wires from the OEM microphone, and then use a new 3.5mm or 2.5mm mono/stereo male jack lead that goes into your android unit. So the original wires goes to the OEM system, and the new wires goes into the Android - like a Y split.
Because the microphone is not powered or an Electrec mic, you will have horrible pick up when your car is actually moving - defeating any of the google voice features while driving. You will need an amplifier to increase the sound going into the Android Unit. Your stock unit most likely already has this built in. HTH

I don't have wiring details for the microphone unfortunately. I'll just try wiring it up with no preamp and see what happens. Honestly the built-in mic is good enough for me right now but it just seemed a waste to not use one already in the headliner

I did try this on my Saab 93. I wired the stock microphone to my Newsmy Carpad3. Mic did not function. Disassembled the stock microphone and found it was active. Took out the active part and connected just the stock microphone element. Now it worked but I had to yell to get sound recorder to just pick up my voice. So I disassembled the radio mic and put the mic element into the stock housing; this allowed me to still use the stock location for a stealth install. Used a Saab connector to connect it as I had bought that to try the stock microphone connected to the radio.

Okay, so I finally got around to doing it with my dasaita px5 unit. It works flawlessly, no amplifier, nothing. People seem to hear me clearly on the other side.

I am interjecting here having personal experience with the Toyota OEM mic on an MTCE. It works however I have variable attenuation between the mic and the HU. Sound quality is not so good on a noisy highway. I often switch to a headset during phone calls. Nonetheless it is quite useful.

Can I just tap into mic+ and mic- and connect to a 3.5mm male connector, then to the external 3.5 mm female port? Do I need to do anything with the pre-amp wire?
Are your problems even with the factory mic the result of the BT chip?
I did not do careful tests of the call quality with the OE Nav unit, so my basis for quality comparison with the head unit is highly subjective, but my current call quality with the external mic is borderline unusable. I have a BT headset while I work out the problems. This is my first head unit install.

I find the oem mic pretty much usable. Speech recognition seems a little more forgiving than the BT chip. On the noisiest roads people have a hard time hearing me. Most of the time I can communicate OK with it.
It is necessary to supply voltage on the red wire to the mic. +5 or +3 volts. And in my opinion the signal needs to be attenuated to reduce overload distortion. This may vary depending on the specific HU. You can probably find a 10db attenuation plug, that should be about right. I use the "mic tester" app to display a waveform and see how well it's working.
I know the OE Nav unit had settings to tweak the mic. I don't know for sure if that occurred in the hu or the mic.

How Can I Upgrade My Stock Scion 4 Wire Mic + Preamp circuit?
Hello, I have a stock 4 wire mic and preamp board that my 2013 scion uses. The sound is pretty crappy and I want to upgrade to an aftermarket one but I am having trouble.
I'm trying to figure out which wires are what on the mic, there are 4 going into the mini circuit board and 2 from the circuit board to the actual mic.
I have continuity from one pin of circuit board to one pin of the mic, maybe this is the ground?
Do you think I could use a normal mic if I found the correct 2 wires and just left the preamp out? Or maybe I need some type of preamp device like this:

Will adding the external amplifier help my situation

Helpful people,
I have bought Asottu CDZ8060 2G android 8.1 head unit of aliexpress for VW Scirocco 2010.
Unit is nice, but I get a constant buzzing noise when I connect a radio antenna (and only when it is connected).
It is always the same intensity and volume from the bootup of the headunit untill I mute the sound or shut down the car.
The noise is sublte, usually it is not a problem, but when the car engine is off it is (a big one).
I have tried:
Grounding a chassis of a radio with GND of radio
Changing the antenna wire from original cable to my radio.
Fiddling with software settings
Putting a ferrite choke over the wire
Nothing helped.
Among all of this the audio quality is worse than with the original radio.
So my wish is to improve the audio (I want it to be atleast as good as the original).
Will external amplifier help with this? Do you have any other ideas how to fix this?
There is a option of returnig this unit and buying a diefferent one, but I am scared that I will get the noise with a different after market radio also.

Dimmable buttons and better sound quality

Hello. Im owner of PX5 Android 9 Head Unit for BMW E46. I know hot to change buttons color but i don't know how to make it dimmable. They always have 100% brightness and it is annoying. Should i change something in radio settings or with the cable connection? 17pins BMW E46 sedan 2003 by.
Other question is - are there available mods or DSP settings for best sound quality? In my opinion this HU sound very raw even with enabled Loud. Previously BMW Business CD53 HU had very soft and warm sound quality. I would like to achieve this on this HU too.

Bump

The lighting wire (orange) from the radio needs to be connected to the wire in the car's harness that does the dashboard lighting. If your radio gets that signal through a CANbus decoder you will have to cut the wire and connect it directly to the car harness.

thanks i will try that.
And any advices for better sound quality? My previously CD 53 had better sound quality (more soft and warm) than this TDA 7851 based device.

The way you hear sound is personal. Your factory HU would have been tuned and equalized to sound that way so you'll have to play with the equalizer to replicate it. The DSP in those units is missing preset effects like you would find on a home theater receiver. You should probably start by making sure the speaker settings match what's in the car like distance and # of ways. If you find the sound too harsh look at lowering the low pass filter frequency and try a different type of filter. You can adjust the PHAT slider to give the sound more volume. Too bad there isn't an easy way to control reverb directly. Then adjust the equalizer to your taste.

Different radio (original BMW) sound warm and soft. This, even with playing on different EQ settings and DSP cant achieve this warm quality. Im using car amp and hertz DCX 165.3 on rear, Audio system MX165 PLUS on front. Everything is connected to amp via Hi_Lo converter. Should i connect this HU with RCA cable? Does this affect on sound quality?
Also are available somewhere custom setting presets for EQ and DSP?

Oh no wonder you're getting a different sound than the factory radio you're using a line level converter. Some people swear they don't change the sound and some other have better hearing and swear they hear a difference. Either way there's no denying basic electronic principles if you drive a signal through coils it will affect the signal more than just reducing the amplitude. It will definitely add/change harmonics and it might not respond evenly at all frequencies. Something like that is probably acceptable to drive a subwoofer. It would take some finely tuned filtering of the output to get the same signal that went in.
If you're using an external amp you should connect it to the RCA's. The problem with these Chinese HU is the line out level is too low they're still living in the 80's when a 1 V line level was standard. Some amps have an adjustable line in maybe find one that works with 1 V.
It might not matter as much but you replaced the factory speakers, all speakers sound different. Usually aftermarket speakers have better quality and sound than factory.

Xtrons D714A - Noise on FM

Hello, I have a noise on my Xtrons D714A when I turn on the FM radio.
If I open an app at the same time, the noise is gone for a short time. When the app has finished loading, the noise is there again. Even with strong local channels.
I think it's a software problem as reception is good when you open an app at the same time. I can't find a system update for my radio either.
Does anyone have a solution for me?

What is your car make and model? Does it have antenna amplifier? How looks an antenna connector which you used to connect into head unit?

Its a Ford Fiesta MK4 from 1997.
I once tested it with an antenna amplifier, but no improvement. The signal is perfect when an app is opened. So the hardware is OK. I think it's a software problem.

What kind of noise is this?? Is it static noise? And only on FM?
I believe that you have OEM amplified antenna, because of presence ANT remote wire
[pic source https://aamidis.blogspot.com/2018/09/ford-fiesta-mk4-radio-wiring-diagram.html]
And if you have good fm signal strength then it means that antenna amplifier is connected and works fine.
BUT
Amplifier also strengthens an static noise. OEM radio has filters to separate that.
Android units don't have such filters because they are designed to work with passive and active(amplified) antennas.
So to remove this noise you have to use something like on pic below, but do not connect blue wire, because you have your antenna amp powered already.
https://www.amazon.com/Antenna-Adapter-After-Market-Stereo-Booster/dp/B07M827R61
I had same issue in my Bmw, which got an active antenna [with external power source. Not by 'hot-wire']
After powering an antenna amplifier I received a lot more FM stations but static noise also increased (due to fact that there is voltage on antenna).
So i connected antenna plug to head unit with adapter like linked above (blue wire left disconnected). It has built-in filters to separate fm signal from static. And since then I receive clear FM sound.
The signal is perfect when an app is opened.

I don't understand. How can it be perfect when you receive noise? Can you describe it more?

Thanks for the answer and the tips. I will get myself such a filter.
The following situation:
The FM signal has static noise. Now I start Google Maps and the noise disappears until Google Maps is completely open. This takes about 15 seconds, after which the noise comes back.
