Is it possible to install a double din aftermarket hu in an 03 no bose/navi A4? Is there a receiver kit out there that will work? I found this one for a single din

If I cut out the middle bar, will I be able to install a double?

theres always a way to cram in a double din into car, any damn car. thing is, sometimes it takes a little or a lot of fabrication. post a photo of what your factory headunit looks like and i'll be able to tell you with more certainty.

what do you plan to do for wiring? I have an 04 and was looking to get the avic z1 but there isnt a wiring harness to go with it any ideas??

you can always just connect the wires if theres no harness, thats always a possibility. you can run some additional ones if u need em or trying to do 5.1 in the car. i will actually end up running wires into my doors for my speaker and tweeter separately

I was thinking about doing that but how do I know which wires connect to which wires in the stereo? im guessing the navi system will tell me which colors out of the stereo are which. Can I get a list somewhere that will tell me which color wires in the audi are which (like battery power, radio, etc.)

theres no guessing, really. those devices have 2 wires and + and a -. just tap into the rear speaker wire by the deck and ur good

alright good. and what about the e-brake if i want to ground it. is that hard to find?

i think u just ground that one onto the chassis
