Hopefully someone could shed some light on this problem I'm experiencing.
I recently had an Alpine 9815 installed in to my Honda Prelude. It's a great HU, but it does something strange that either my self or the shop that installed it can not figure out.
Every once in a while, when I go to my car, the display on the HU will be on. No music plays, but the display it lit. There is a direct line from the battery, and a dedicated ground. I have also checked to make sure that the illumination is connected to the correct wire. The shop that installed it even swapped the HU for a different, but yet the problem still exsists.
Does anyone have any ideas??
Please help, I'm getting pretty frustrated.
