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 Tropingzz Cece

Checked here three times whether it fits my Audi. They said it will fit. but here, too, 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 test them out before just connecting.
