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!

scheme elettric microphone and speakers

Hello!
I enabled the aux input of my car radio and wire a cable jacks.
the problem is that when I get a call from my htc hd2, the sound is heard from the speakers but does not work the microphone for conversation because the hd2 course off the microphone of the device active because the headset with microphone.
Is there any way to wire the cable jack (4 pins) and attach a microphone to the cable itself? Some might suggest a scheme electricity?
thanks!
:sorry my bad english

In theory it should work as long as you can get the components and wire the cable correctly. whether or not your mouth would be too far from the microphone might be an issue,

Unfortunately, if I connect the phone jack, hd2 excludes the microphon base to activate the headset that is built, then the conversation can not happen, but I feel he did not hear anything

should understand how the microphone is connected to the headphone series

Depending on where your phone is, you could use a regular 3.5 mm male to male extension going from your radio to the phone. I have mine set up like that and the mic on the phone itself is powerful enough to pick up your voice. I ran a 10ft cable(3.5 mm male to male) from the radio,under the instrument panel, up the side of the door in the molding of the windshield to the sunvisor where my phone is clipped to the visor by the clip on the case. It works fine but you have to adjust the volume between your phone and the radio to find the best combination to avoid major feedback so the caller doesn't hear his own voice echoing in the background. I can't post links yet but if you go to youtube and search "iphone handsfree iphone in car setup" you will see how I did my iphone but I now have the same setup with the Hd2.

Eonon GA2171S processor/wifi noise interference

Recently installed a GA2171S (Px5 double din Android 8 4gb ram 32gb rom DSP version) into my Nissan Juke and quite happy with it. The built in amp and DSP module functions are nice. Factory subwoofer and speakers work well with it and subwoofer output RCA does work in this model perfectly. As a DIYer, I popped open the unit and installed a 40mm heatsink and fan to the SOC to keep it from thermal throttling. I found a 5v power lead on the board to snag power from for the fan. Keeps the fan at a lower RPM and inaudible.
My issue with the unit that I would like to improve is to try eliminating the processor noise that is produced out of the high level speaker wires as well as the RCA audio output connections. At first, I thought it was only the wifi activity I was hearing in the speakers but even with wifi disabled, I can hear a bit of processor noise like onboard audio was infamous for on cheaper PC motherboards.

The wifi coax cable is very thin and cheap, it was routed and taped to the DSP module. I rerouted it away from the DSP chip and dramatically reduced the wifi transmission interference but it is still there. I am going to replace the wifi coax cable with a high quality one with SMA connector to attach a proper external 2.4ghz antenna to hopefully eliminate wifi transmission noise in the audio and make wifi far more functional. Right now, when I am parked in the driveway I can barely get my music to sync even though my wifi router is just 25 feet away. The head unit has no issues syncing the same music when hot-spot connected to my phone a few feet away from the unit.
What I need input from you guys is, what kind of non-conductive materials exist in order to wrap the DSP module with to eliminate RF interference from being injected into the audio. Been researching but not finding anything too straight forward.
Thanks for any input!

Hi! I have the exact same unit and I am wondering if this is due to ground issues with your vehicle?
I too have opened my unit and installed a heatsink, rerouted the wifi and gps antenna wires, also I have replaced the amplifier chip with a Pioneer PA3020A. I have never heard any processor noise, coil whine, wifi interference etc. before or after making these changes. My car is a Toyota FJ Cruiser.
My always connected devices:
WIFI: Huawei E8372 LTE
BT: OBD-II adaptor and Note 8
USB: TPMS receiver and DAB+ receiver
RCA: Reverse camera and dash cam
Another thing you can do is try turning down the amp gain. In 'Factory Settings' > 'Other' there is an option to change the amp gain. Try changing it to -9db and see how it affects things.
Good luck mate!

I have the same problem, the eonon support spreads out the hands.
I connected the radio directly to the battery. No changes.

Interesting. I cannot get that noise to go away.
Have you found out whether or not the interference noise might be produced from the low level RCA jacks, too?
Something to note, I did install one of these same units in a friends' Juke a couple weeks ago and there is NO interference noise what so ever. Difference between her car and mine though is that mine has the Rockford Fosgate audio package with 2-3ohm speakers where her basic audio has 4 ohm speakers. I wonder if it could be an impedance mismatch causing this noise.

There is a lot of dialogue on the Miata bulletin boards when you try to integrate a new head unit with the upgraded BOSE amp systems. The low impedance Bose Speakers cause mismatches when you try to use the BOSE amps with a new head unit. I have done it several ways, using the RCA jacks (not enough output) and using a matching device that takes the RCA jacks to the front end of the BOSE amps.
What I ended up using is https://www.amazon.com/gp/product/B000BFL52Q/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 with plenty of grounding and some ferrite cores on the signal wires.

I just installed this unit as last night in my Corolla, standard audio which is 4-ohm speakers iirc, and still get the interference I might open the box and see if I can relocate the wifi antenna, or just replace it outright as well.

Have anybody found a solution?
I just bougt this unit and have lots of static (wifi cpu ...) noise.
Tested the unit in my home on my home stereo using a stable power supply, and just the same problem.
noise on both rca (low output) and from the unit amp...

I too have the same static noise issue. I suspect it is coming from the RCA. Have you found the origin or a solution to this interference noise?

I bought a strong wifi cable RP-SMA but I haven't installed it yet. The sound comes from the wifi module. When the wifi is off, silence is switched off.

Do you think it's possible to resolve the noise interference issue with MTCU update?

I think it's a hardware problem and it's just a normal interference by wifi radio waves.

In my case it looks like the noise is coming from processor as well as wifi module. What is your MCU? Is it WWW?

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.

Buzz sound help

Hey guys. I have a Joying headunit and recently i was on a call via bluetooth and the other person said they can here buzz sound so I decided to do some test and started voice recording on the headunit and found out that when car parking lights or headlights are on, it records that buzz sound. Lights off and the sound is gone. Anyone would know, why?

Wen you say you were on a call with BT, can you clarify what you mean. You had a bluetooth headset on in your car connected to your HU? Your HU was getting getting phone call how? Also BT? to you phone? Or you mean your HU was BT to your phone but you were using the HU mic? If your sing BT headset that seems odd and more likely an issue with your headset. IF however you mean you were using BT to connect phone to HU(aka handsfree) and you were using the HU mic(or external mic) welcome to the chinese head unit party. The mics and the internal components are poorly shielded from engine and other electronic noise. Only thing you can really do is buy a better external mic and see if it helps.

That's typically from too much power draw in your cars electrical system. Which can also mean you have some poor grounding. It doesn't hurt to start adding ground straps all around the car. Ground battery to chassis, ground block with ground of battery, ground body with block etc. Inside the car behind the head unit, you can ground your ground wire with a T connection to somewhere metal in the dash. That will help with the buzzing sound while your lights are on and functioning.

well if he's talking about sound on a bt headset,that's something very different, but I assume he meant standard hands free.
