i have an audi a4 and i got an f700bt professionally installed. since they installed it I hear white noise coming from my speakers constantly. Is there a way I can fix this or should i bring it back to them. I really dont want to go back to this place because I didnt have a good experience and I dont want to pay another place to do it.

Second question: Is the hack to make it work without the parking break easy to do? could I do it in like 20 minutes with no experience what so ever?

no clue about the white noise but..

you can do the bypass in 5 minutes with no experience. its relocating one wire and grounding 2. you'll spend more time getting the unit out

jus follow the instructions in the first post and you'll be fine

ok, how do I get the unit out? I took off the faceplate by prying it off w/ a screw driver and there was a black goopy stuff that they put on during the install. what do I do beyond that?

every car is different man ive never even sat in an audi. you can search audi forums to see if theres a step by step or maybe an A4 owner on the forum will chime in, but i have no idea how it comes off

If they used a Black goo to attach the trim or face place then it sounds like they broke something or didn't attach it properly.

if you are geting a noise through your speakers when you take it apart let us know whether its hooked up through hi-level speaker leads or low-level rca's. also let us know whether you have the bose symphony system or base system. also whether the amps are bypassed or integrated that can help us give you a clue how to go about fixing the sound.

That sounds pretty scary. Are you sure you didn't pry off the front of the AVIC itself!...

Yeah... "black goopy stuff" should never be part of any step in installing a head unit...
