This unit fits the 2002 - 2008 Audi A4 models. It will not matter if you have Bose or the Audi Symphony factory radio you are replacing. This unit comes with everything you need to do the connection correctly and it has plug and play adapters for your factory harnesses. (READ BELOW FOR MORE ON INSTALLATION) Great radio with a smooth responsive touch screen. It uses Android for it's operating system so you can load apps on it too. The Apple car play works great. Connect is easy to the phone. Tons of options, so take your time to learn it screen by screen to see what you want to use. Sound quality is very good with adjustability to your preferences.INSTALLATION: Take the time to go over the included parts list. A picture is in the listing of what is included to help. This is a run down of the parts included by pictured part and number.#1 - EXTERNAL MICROPHONE ( Helps with road noise and can be placed by instrument cluster or visor )#2 - GPS ANTENNA ( Used for the internal maps system navigation. Use with #8 for mounting )#3 - WiFi ANTENNA ( This unit can make its own WiFi signal for phone pairing NOT data )#4 - DISASSEMBLY TOOL ( Helpful with removing trim pieces when routing wiring like the microphone )#5 - CANBUS ( This plugs into #10 and may already come plugged into either harness. This allows you to use factory steering wheel controls with this radio like the factory radio does )#6 - RADIO ANTENNA ADAPTER ( This may be needed to plug the cars antenna into this new unit )#7 - 15AMP FUSE ( extra fuse in case you need it )#8 - 3M STICKER ( Used to mount the GPS antenna )#9 - DISASSEMBLY KEYS ( 4 tool keys used to remove the factory radio to install this upgraded unit. The curved side faces in when inserting them into the 4 slit openings on the factory radio. Insert until a click is heard, then use them to pull the factory unit out of the dash. Sometimes the keys do not unlock the factory radio so it can be pulled out easy so take your time as you might have one or two not want to release. If this happens, pull that tool key out and reinsert till it releases the lock. It may help to pull from the tape deck opening with a couple fingers instead of pulling from the tool keys as they tend to pop out if pulled too much )#10 - POWER CABLES ( These are the harness adaptors to take the cars harness to the new radio. There are 2. You only need 1. You need to select the one that fits into your factory harness that was plugged into your old radio. Remember to have CANBUS plugged into the harness adaptor you are using out of the 2. This harness NEEDS to have all of it RCA cables plugged into the back of this new unit for sound to be sent to the speakers. Read on the back of the upgraded unit for proper plug placement to have the sound sent to the correct speakers. Take your time with this part to insure the unit plays sound out correctly. You do not need any other plug in boosters, you just need to connect this correctly. )#11- RADIO ANTENNA ADAPTER CABLE ( You may not need this. This adapts a 2 pin plug style antenna to this radio )#12, #13, + #14 - USB ADAPTER CABLES ( These plug into the back of this upgraded unit to give you options of having a USB connected device plugged into the new unit. Works for Android phone to connect via cable. Can be used as a USB plug in charging source. However keep in mind this will not be a fast charging type USB plug in. )A manual is stored in the new radio for on the go helpful learning.A good suggestion is not to fully push the new unit back into place until you have all your connections done and it is tested to be working properly.Take your time with the install so you can enjoy this new unit and all the feature that will really take your B6 B7 AUDI A4 to the next level all for a great price.Thanks AMASEAUDIO !

The unit is AMAZING. The DSP function helped me tune the radio to my preference. CarPlay works like a charm! Note, my car has the semi amplified system with a factory sub. I had to wire in a line level converter for the rear speakers to work properly but wasn’t a big deal, YouTube helps a lot.Again, unit is great, responsive, looks OEM. Brought my car to the modern era and the support from AMASE audio was perfect.

If your like me and the zlink app just sits at "waiting" while on your phone it says "connected to car" try this.1. Go to your app settings for zlink in the headunit then select "delete cache and saved data". Afterward, when you open zlink it'll give a message to reactivate, and to connect to the internet.2. Open a Hotspot on your phone3. Connect the headunit to the Hotspot using the wifi.4. Open zlink and do the reactivation process. Select your "carplay/android auto, wired/wireless" combo your going to use it for. Let it activate. Then do the setup process again.Before this I tried everything. Forget bluetooth, wifi, reset etc. The unit connected once when i first installed it then never connected again until I did the process above. Now it has connected every time within 10 seconds of key turn on.On to the review....LOVE the unit. Best 200 dollars I've spent on any audio upgrade on any car I've owned. The best part is that the unit is literally plug and play. No wires to solder or crimp. Everything is supplied.For the features you get it really is worth it. You sit in the car, key on, and within 10 seconds your music auto plays (can change that) and Google maps opens up. You can also install a back up camera which I plan to do later. You can change the ambient lighting color when you turn your parking lights/ headlights on to any color you want. I stuck with red to match the rest of the car. Just having an android system is a HUGE upgrade over the stock unit.As for the gps and wifi unit, I didn't run them anywhere, I just kept the wires coiled up and stuffed everything behind the headunit. I didn't see the need to run them anywhere. I'm not using the external mic as everyone I've talked to over the phone says they can hear me very clearly using the built in mic on the unit.Having Google assistant is great as well. Just like your phone you can use voice commands to do alot of stuff. Navigate, call, text, open apps etc.Overall an excellent purchase.

I love that it still looks stock in the dash and made my speakers really come alive with very impressive low end. BASS 🤯 BOOM 💥The only part that I had to replace was the antenna adapter the one that came with it does not boost the antenna signal but after a quick stop at a local audio shop I got the correct powered antenna adapter. Amazed how good it made my speakers sound.

I like the stereo easy to install and it works really good.The only problem I have is that I try to connect a back up camera and I was not able to take the unit out the removal keys are not locking and the stereo is stuck in there.Really disappointing.
