Help.. not getting power through the 'constant' feed for the stereo
trying to install a new head unit in my A4 (2005 B7 - Symphony II), all is well apart from the voltage coming from the 'constant' feed, it seems to be between 4-6volts instead of 12V - and the unit won't work without 12v from both the ignition and constant...
My Symphony was working fine, memory ok etc..
Thought it may be the fuse... but can't see from the manual which one it would be and don't want to take them all out...
Any help really appreciated..
