[Q] Nexus 4 Mirrorlink and Miracast - Nexus 4 Q&A, Help & Troubleshooting

Does anybody know if the nexus 4 supports mirrorlink?
I've managed to get an N4 for Christmas and I'm now looking to get a good stereo for the car to pair it with. The only info I can find about the N4 is it has miracast which seems to be different to mirrorlink but I'm not sure how.
I'm not particularly a car stereo buff but it seems like a number of companies (Sony, Alpine, JVC, etc) have released headunits with mirrorlink. It looks like quite a cool technology and would really be useful for Google navigation on the stereo screen. However if it isn't going to work, I'll give up and start looking for a cheaper bluetooth only solution.
Thanks

I went to best buy to test this out on a Sony head unit with mirrorlink and it didn't work. I used Samsung drive link app.
Another option is to get a miracast adapter with a hdmi to rca converter to connect to the head unit. But you will only be able to control apps from your phone. But at least your phone will be mirrored on the head unit.

Thanks for trying that out, I'll keep my fingers crossed for mirror link in the future.
I really like your 'hdmi to rca adapter' idea. I will give that one some serious consideration, however if it works on this stereo my guess is it will work on others as well (back to looking at other stereos again, I thought I had narrowed it down).

Has anyone tried this? I'm also in the market for a good Headunit and If its not going to work on MirrorLink I wonder if it works using the hdmi/rca adapter.

BlueTooth In-Car Audio with the A500?

I was getting ready to burn a new Rob Zombie CD but I thought of this and wanted to ask the guru's if it might work!
I did a little research and found a few devices that I "think" might work, but I'm not 100% sure of the bluetooth capability of the A500 (does it have the correct profile to do this?):
TuneLink Auto - http://www.amazon.com/Tunelink-Blue...2?ie=UTF8&s=electronics&qid=1305375956&sr=8-2
GOgroove Flexsmart - http://www.amazon.com/Transmitter-H...berry-Smartphones/dp/B003PPGOC0/ref=pd_cp_e_1
Has anyone ever used a type of device like this? Any recommendations on the best one to get?
Thanks in advance for any help!
-edit-
I went ahead and ordered a couple:
The Soundfly BT: http://www.amazon.com/gp/product/B001DDE4VY/ref=ox_ya_os_product (will have it Monday),
and The TuneLink (will have it Tuesday).
I'll post my findings once I give them a test!
Bluetooth FM transmitters? My experience with FM transmitters taught me one thing.... with buy a new head unit with aux in or bluetooth directly. But I have yet to try my a500 via bluetooth in the car, maybe later today

The iconia has the capability, that is sure. I paired it with the bluetooth of a rented car and the music of my iconia played perfectly. I could change songs and volume with the steering wheel controls as if I was reading a cd.
The car was a Peugeot 308, using poweramp in the iconia. 4 hours if pleasure drive in France listening to my music, and with very low battery drain.

Great, thanks! I look forward to testing it out next week to see how it works. I bought two different models and will give one of them to the wife (after I decide which one I like). LOL
I have two of them, and much cheaper than what you paid.
First one i bought was an Alpine EX-10. I got it on amazon for 30 bucks. It allows bluetooth transmission through line-in aux or fm transmitter. there's ALOT of wires though, but it comes with a remote as well and a mic for speakerphone.
The 2nd one I bought, which I am using currently, is the Kensington LiquidAUX. I think I paid like 20 bucks for this and it works great. Very little hardware and cables and works perfect. Has a remote and steering wheel mount. It only works through AUX-Line-In though.

Screen mirroring and phone control?

Hey guys, I usually just lurkj the forums but I figured it is time to ask the pros. First off, this is the unit I am installing today: Seems i cannot post the link but here is the title. from amazon Pumpkin Quad Core 7 inch 2 DIN Universal Android 4.4 Car Stereo Radio HD 1024*600 Muti-touch Screen GPS Navigation Without DVD Player Support WIFI/3G/Bluetooth/OBD2/DVR/Mirror Link
I am running a t-mobile service on my phone and I get free data for certain streaming apps. Its pretty cool. Anyway, I just learned that using the phone as a hotspot and then using one of these streaming apps on the device, in this case the new stereo, it does use my data plan... bummer. Anyway I am wondering if there is a wireless mirroring solution that would work and have control over the phone using the touch screen on the receiver? If there is not, how about a wired solution? I have looked into things like android auto. Does that actually work descent and on our receivers? Thanks everyone and a little nudge in the right direction would be awesome :good:
The pumpkin deck has a really basic bluetooth audio interface. I guess that would be the main thing I would like to change. I use Pandora alot and the interface on the deck is really basic. It gives me the option to skip track and play/pause. If I could at least get a similar interface to my old pioneer deck (id3 tags, thumb up/down) that would be cool. Or even a front end app, now that would rock.... Thanks again.

This unit is the same as pumpkin RQ0255 unit. There is more information available from their support page and is directly applicable to the Naviskauto unit you have.
I installed this unit with a Metra dash kit into a 2003 G35 Sedan with Steering wheel controls (kit required) / the stock Bose amplifier (audio interface kit required) / and reverse Cam. All the functions you want are available. I assume you want to connect iphone/ipad via bluetooth , it works but the bluetooth interface for music isn't great , and maybe a 3rd party app is available. There is an "IPOD" USB connection through a 30pin connector. (Overall, music quality is very good but not as good has name brand head units for USB/Bluetooth/Radio. ) I use an Iphone 4 as an Ipod over USB, but you should be able to use a lightning convertor cable and use newer iphones/ipods. The music interface is better on USB but still falls short if you're looking for iphone/ipad useability. You can connect the head unit to a wireless hotspot on iphone/ipad or any device with this function. You can also connect via USB to a 3G dongle but the supported devices are limited, (more reading for you.)
GPS works great and the iGo Navi app provided is really good and does not require an online connection. You may need to do some more reading to get maps / poi functioning to your needs depending on your location.
It's my first android head unit install and it was flawless for me. I invested lots of time reading to extract experience from this board and others I am generally familiar with car sound systems, electronics, soldering so I was just a matter of understanding the wiring interfaces for this unit, which are standard.
I'm a newbie on Android , so I'm not experimenting with ROMs yet but there is a ton of info on what is possible with mods and replacement apps for various functions.
so, bottom line, I give the unit a 8/10 overall, but the value for money from Amazon I give it 9/10.

Thank you for your information.You're more experienced than me as I can tell. According to the review,it seems a good choice.I will look at more and make a "experienced" choice,I think.thanks again,man.:good:

"seicane" aliex - PX3 7.1.2 Bluetooth music A2DP quality poor

Hi guys..
Well first of all how I wish I'd checked these forums first before buying as I wouldn't have, second I wish I'd at least bought from the UK as I'd get some support. But hey ho I didn't and I'm stuck with it as returning to china seems to risky after the message suggested returning at a value of $70 so they don't get taxed and also making sure its sent by EMs so it doesn't get lost in transit like many units do at customs!!
So I bought what seemed to be an all singing all dancing unit from seicane store on ali express, for my seat ibiza mk5. According to the system info via root check app it's a px3, 7.1.2 android, rock chip, rk30sdk.
Amongst many other problems my main one is the Bluetooth audio quality over A2DP is horrendous, and it's not an amp problem as over aux or USB it's perfect. I've been looking at airplay using air bubble app and personal hotspot but it's too long to load and unstable I only drive 15 min to work so just want fast music to my ears! I've considered getting a Bluetooth transmitter and sticking it in the aux input but not ideal.
Anyone got suggestions as to what the issue may be and if it can be resolved?
Thanks in advance hope I can get this stable one day!
mine is also horrendous, and I also have a very short drive. Connecting a hotspot and launching app and getting a song, takes just too long for me. I'm basically already at my destination by the time I get it up. My workaround was to do what you said, and get a bluetooth transmitter and sticking to the aux, because aux sounds fine, but just bluetooth over a2dp sounds so bad, and has this distorted high end sound. This solution worked for me for awhile, but the only downside is you don't get song information on the head unit to display, which is a tad annoying for me.
I've contacted my radios reseller, and they're just ridiculously helpless, all they do is keep sending me a "software" update to fix it, but it does nothing. I've been searching for over a year for a solution, but have found nothing to fix it, other than what I just said. Problem was still there even when I used custom roms. SO I don't really think its a software issue, maybe some kind of hardware I can replace or modify, but I just really have no clue.

Yeh I've ruled out airplay as an option,
you've got me interested though as you're in a similar boat as me so hopefully can help, do you have the exact same unit for an ibiza or?
And yes thats exactly whats annoying me not getting track info, may as well just use the original head unit if i get a bluetooth transmitter!! which transmitter did you get? i've got a really cheap basic one years old and its got a high pitched whining noise in between song skips so its there just muffled out by songs playing, I'm wondering if thats probably just a cheap receiver I've got..
I'll try get somewhere with the hardware see about a new bluetooth module but no idea on the interface would be total guess work and risky at that, not even sure how to safely root this one.
Other issues i'm having which may be common and you may know? I got a dash cam which cam with a yellow RCA, an Acc+ wire, a ground wire and a 12V wire.. i don't understand why its got an Acc+ and a 12V, i thought similar things both transmit power just one off the ignition being on only? theres no 12v out wire on the head unit except 'cam pow' which I've tried to no avail. I plan on recording direct to the SD card on the camera.
Subwoofer out, does this work on our units? i bought it because i plan adding a 4 channel amp for F/R speaks and a sub amp for a single sub.. but does the rca not work / no amplifier control over it?!
Cheers hope to get somewhere with this as i feel a bit down that its not all singing all dancing like i expected lol.
i have a Seicane with Android 6.0 already, which I dont really have any problems with, but it is not PX3
however, I do have a Seicane with Android 7.1 on the way that does have a PX3. I'll report back when i get it to see if I have any issues

your bluetooth quality is as good as aux? i wonder if its a software bug..

Well the 6.0 version is totally different hardware
it is a known issue that no one seems to have a fix for. Im having this same issues with my PX5 Dasaita unit and had this issue on a previous Xtrons unit aswell. I believe it is a problem with the bluetooth drives not supporting the higher bitpools of recent bluetooth updates hence the bad quality. Ive even tried installing a USB bluetooth dongle but could not get the unit to recognize it.

Well I also have a Dasaita PX5 and I definitely didn't have a problem on that one. I would listen to Bluetooth audio on it pretty regularly.
Quick from Hot Audio did email me and ask about it, saying they had heard complaints, and sent me a new harness, but I haven't needed it

Well i've gone an ordered a car play dongle, so hopefully that will be a solution for good radio and a more functional nav at the same time.
Any tips for the dash cam guys? i ordered the 3 cable power one rather than a usb to keep the slots free.. not sure where i should hook them up to. (12V yellow, Acc+ red, black Grnd), i've only got an acc+ on the back of the harness and ground i made an earth wire to the car. Left the 12v off and it doesn't turn on. but my unit doesn't have a 12v, only acc+ or cam pow.
Got a pic or link to the camera you got?
So i have this camera..
https://www.aliexpress.com/item/140...32812106756.html?spm=a2g0s.9042311.0.0.MXwOS4
and this unit..
https://www.aliexpress.com/item/Aft...32827061575.html?spm=a2g0s.9042311.0.0.MXwOS4
The seller said to connect acc+ to acc+ on the unit, 12v to the cars 12v and grnd to the cars ground. I made an earth for the ground just to a screw towards the rear inside of the dash, but not sure where i'll safely take 12v from? especially with the car having a can bus if i splice any wires that may cause an error? Surely these units put out a 12v signal somewhere?
heres the wiring diagrams... https://ae01.alicdn.com/kf/HTB1z7DmnMn.PuJjSZFk763_lpXaZ.png
Also another Q regarding using an external amplifier for speakers and a sub.. is there an issue with the actual volume sent to the amps and can this be resolved? depending what input i give the head unit the volume differs, aux a lot quieter than usb stick or bluetooth.. but even both of them at volume 30 neither are really very loud where you here the speakers distorting, with a standard radio or branded head unit towards top end the speakers would distort so i can set a 'safe' max limit, my concern is the android head unit will limit the amp? and i've seen no info on rooting these units for viper4audio if that would help.
Thanks
Edit: how would i check if the 'cam-pow' wire is putting out 12v with a multimeter? just hold one probe to the wire and touch a ground point with the other?
BT & USB Support on PX5
Guys,
Sorry to tell you, the ROMS are very stripped down and as a result, the only support will be for the listing of BT modules that are on the main board and only for the ones list in the setup. You will not be able to add an external usb BT module to the head unit, it will not reconize them, and therefor will not work. Same with other USB devices. All support has been stripped out of the firmware. Some of these company's are getting slick enough to modify the firmware even more to only support devices that they sell, locking you into buying there junk. Good Luck! I had a BT problem with a Seicane Head Unit, and tried every possible, BT usb module only to find out what they do. Anyone want to purchase BT usb modules cheap!!!!!!

HIZPO unit, where to get TPMS, TV tuner, etc...

Been messing with this unit since it came in the mail till its ready to go into my truck. a lot of the front ends remind me of my carputer days, still have 2 MP915's!
Where do I get a TPMS and tv tuner for this thing? Just any ol usb tuner works?
What about the DAB+?
Changing the resolution, the ad said 1024x768(?) but its at 800x400(?)
Better than stock apps?
Hows about a much better control for the RGB LEDs?
Obviously ive been out of the game for a few years. Also, how do I make the camera turn on when I put it in reverse? And turn on the correct camera direction? Many thanks everyone

hey! I´ve seen tv box, DAB+,CARPLAY usb dongle at amazon.com
The store from where I got my hizpo is HAITU TECH.
good luck!
well if its like most chinese headunits the Bluetooth is crippled you wont hook anything into but a phone and apparently none of the nerds here know how to hack it
honesty always appreciated!
