Recently installed an 8000 into my 07 Volvo XC90. 

 

Was working fine, but I was out driving about a hour after I completed the install and it restarted twice, but then stayed on the entire time for close to a hour with no issues.

 

Today, it was restarting like it had been but after one of the restarts, it stayed on the Pioneer loading screen with the audio still playing in the background.  I pushed the reset button and it stayed on the loading screen, with no audio.  It also sometimes tells me that the handbrake is connected improperly and some times it doesn't.

 

I have the parking brake lead grounded, along with a parking brake lead (negative) on the harness.  The VSS wire is also connected.

 

I soldered and used heat-shrink tubing, so my connections are solid.

 

Any help out there?
