I'd like to sythesize some of what I've read above in the sticky post to make sure I have it right. If I'm going to break down and put in a new head unit for wattage and so I have a cd player and mp3 input, this looks like what I'll need:
1. Wiring harness: I take it I will have to butt end connect the purchased harness wires to the aftermarket head unit wires, then simply plug the harness into the factory 16 pin harness that the oem radio unit just pops into.
The most basic I could get by with would be this one for $8:
I take it that with that harness II would lose my chimes, and also the radio would stay on when I turn the car off and get out of the car, until the ACC dies on its own 5 minutes later? I'm taking this to mean I could lock up my car and the radio would still play for 5 min. if I didnt power it off before I left the car?
Or, I take it that I could solve that issue with this harness for $80:
2. Antenna adapter: Use the VW one, which I don't have a link for but imagine it'* not too hard to find.
3. A 1.5 DIN aftermarekt unit looks like it would slide in, and I could take the factory clips off the OEM unit and attach them to the aftermarket unit, and pop the unit in with no additional mounting kit needed. (For a 1 DIN unit I'd need a mounting kit, but for 1.5 DIN it looks like I can go without.
So, does this sound about right?
