I didn't wire my harness or the bypass myself, got it used from another guy with a VW.
My issue is that the bypass worked no problem for the first few days after I installed the AVIC-D3... but now I got a warning on the screen when I was on my way into work this morning.
Think its wired bad?
The other thing I'm worried about... it came out of a VW that had a traditional e-brake, but my Passat doesn't have that, its got an electically controled parking brake, you press a button and it closes the calipers on the brakes. Logically I think the bypass wouldn't be affected by this, but I'
