Has anyone installed a new audio in 2010gl?
Installed new Pioneer AVIC head unit in 2010 GL450. Since then, radio reception is horrible due to the factory antenna amp not being powered. Since nobody makes a wiring harness for this vehicle, does anyone know which lead powers that antenna amp behind the radio?
Funny, but I have the same EXACT problem in my 2007 SL if anyone know that wire also.... Thanks!
