Review on 🚗 Complete Car Stereo Install Kit for 1996-2006 Audi A4, A6, A8 & TT - Enhance Your Audi's Audio System with an Aftermarket Single Din Radio by Dan Bobbert

Checked here three times that it fits my Audi. they said it would. but then again, they were wrong. The connection diagram is incomplete for the kit I ordered (the powerful antenna is not yet included in my kit. There is no indication of what went where). i am not new Maybe my 50th stereo. I know the red wire is on/off and it says so in the code. BUT, lo and behold, on this kit it was the BLUE wire that was on/hot. I'm glad I'm smart enough to try them before I just plug them in.
