Pioneer 860mp troubles...again

I've been having trouble with my head unit for the past couple of months. For some reason the face won't flip down, I can't eject cds or even pull the deck to send it somewhere. I've taken my truck into a stereo shop back home, when this happened last month, and they said all they did was push the reset button. I had done this countless times prior to taking it in. Once again I've tried resetting it, disconnecting the battery, and pulling the stereo's fuse. I go to school about 4 hours away from my hometown, where the stereo was installed, so it's a little hard for me to take it back to them.

I called Pioneer and through the broken english the rep was speaking, they basically told me to take it to "an authorized Pioneer technician." I called various places around here and nobody could (wanted to) help me. One other problem is the fact that I bought it online, so my warranty is worth crap. My only glimmer of hope is that the shop kinda knows me and is under the impression I purchased it from them. I'm so sick of listening to the cd stuck in there, and it had to be one of my girlfriend's mixes, total crap!  What can I do at this point? Thanks for any input.
