I just installed an after stock radio and it was working fine for a couple minutes, then all my intior lights went off. Like the odometers back light and brake lights and my fog lights don't work. Also my service vehicle soon light came on. Can anyone help?
 
Probably a fuse blown or something shorted out. Did your GA originally have the monsoon sound system? The monsoon system has an amp mounted in the trunk, your new head unit might not be compatible with it.
