I'm new to this and not exactly tech savvy. I have the F900BT for about 2 years in my truck. Always great. Yesterday, out of no where, it started to keep shutting off and on. Lasted about 3 minutes each time. Then it would do it again. I called Pioneer and after waiting on hold for LITERALLY 30 minutes, I was told it's $230 to fix it flat-rate. Told me its a software problem and nothing he could do. Very arrogant dude. Anyway, so here i am. Any help? Pleaseeeeeee I operate on an Mac. I see people post links and I know Apple can be difficult. Thanks to anyone who can help!!
