HELP with headunit installation
I've got a Pioneer DEH-5550MP (i think), i installed it yesterday, everything was fine, was working perfectly. I went inside for a while then went to go to work, start up the car and nothing. Antenna didn't go up or anything.
When I got to work, i had a break so took the dash off, wiggled around the wires at the back because i thought it would just be a loose connection, which it must have been because it started working again.
I thought i'd better solder the wires then, so this morning thats what i did. Hooked it all back up again and it's all working sweet.
I go back to my car to go to uni, and nothing. Doesn't turn on - exact same thing as happened the first time. I just rewired it so couldn't be a loose connection, i didn't know what the hell was going on.
So, bugger uni i'm gonna try and fix this. Took the dash off, looked around, used a multimeter and the headunit is getting power properly but its just not turning on. I tried disconnecting everything except Constant 12v, ACC 12v and ground, but still nothing. Even tried running a ground straight from the battery with no luck.
Does anyone know what the problem could be? I just got this headunit for my 21st and I really want to get it working.
Whats wierd is how it was working 100% perfectly, i'd turn the car off, then back on and its still sweet but now it's not doing anything!
However - the eject button makes a "beep" sound when pressed, and when i turn off the ignition, it does that 5 beep thing to remind you to take off the face.
Any help greatly appreciated thanks guys.
Oh yeah, the car is a 1995 EF Fairmont.
The fuse on the back of the headunit is fine, as is the ACC fuse in the dash.
