Android 9.0 Double Din Car Stereo for Audi A4 2003-2011 HD 7 inch 2G RAM+32G ROM Car Audio GPS Navigation Head unit Support WiFi 4G Bluetooth Steering Wheel Google DAB OBD Free Backup Camera & Canbus

Bluetooth disconnects by its self

I love the stereo but I have a 2007 A4 Cabriolet with Bose, I was able to get 4 out of the 6 speakers working, any advice on the wiring?

Horrible product. Comes with zero directions and the radio on mine. Does not receive any channels in either am/fm. Also had to spend twenty dollars in two attempts to make the oe antenna adapt to the radio. With no luck. Also I had to figure out on my own that the sound outputs are provided by rca connections. I tried to contact the manufacturer with no luck. Garbage spend the money on pioneer. I have a ten year old pioneer that sounds 1000 times better than this unit in my other car. Hey at least now I have a rear backup camera and Bluetooth 😂

I just installed this yesterday, I plan on going thru and testing it completely and updating my review. So far I can say it’s pretty nice. The fit and finish is nice. Not a exact match to OEM. But is extremely close. Start up is pretty quick. Close to a modern VW/Audi MMI. Shipping was very fast with Prime.The good:Great fit and finishEasy to use, just like any android phone or tabletFast shippingThe bad:Needs a car play/ Android auto USB dongleNeeds a antenna adapter for FM/AM bandThe radio keys have very sharp edges and will cut hands up if not careful(wear gloves if you don’t want cut up fingers)

Looks like a factory unit once installed. Works well with the Audi Bose Symphony, just took a minute to figure out the speakers are connected via the RCA's. Sounds good enough and paired with the phone easily. Nav works too. Overall a nice upgrade for a 2004 A4 Cabriolet.Update! Looks great, fits great doesn't make up for the sketchy behaviour I'm now experiencing. Screen goes blank and sound disappears. Nothing.

works very well, looks complicated to install but isn’t too bad at all. only issue i had was with installing the reverse camera, i can’t seem to get it wired correctly. i also didn’t know an apple USB cable had to be ordered separately in order to use apple carplay. all in all a great proud though, sleek fitment, OEM look, i can even download little games on this thing.

This unit is cool, it has all the features you could want and then some. However, the quality is absolutely terrible. Sound is sub-par and even worse, its loaded with interference. The unit eventually just stopped working and gave me the blue screen of death the same day of install. These units would be great if someone would just take the effort to put legitimate quality in them. This was to replace another unit I owned thats similar, just older so it was a super easy install for me, just plug and play. My last one also was below average in sound quality but at least worked and didn't have interference. This could have really been a great product but just walk the other way and buy a quality system. If you could get it for $100 or less then its worth it and maybe yours wont be riddled with noise interference.
