since i had issue with it 3 days ago (too cold here didn't start just reboot every 15 sec) it doesn't work very well ever since.

Today wasn't cold at all... the unit was starting nicely but after 30sec of music... it just reboot over and over again.

i have v3.0, never problem with it. I tried reset too. any ideas?

i hope it's not a brick... btw 3.0 was installed 3-4month ago, never had problem... version from here...

i removed:

gpspara0.bin, gpspara1.bin, gpspara2.bin and gpspara3.bin and it works so far

I'm having a similar issue. My f500bt is NON-modded and when my phone is paired (BT) it would reboot. I sent it in to Pioneer and they said that nothing was wrong with it. As soon as you disable BT on the phone, the reboot cycle stops. I've upgraded the firmware and BT on the device to the current release. Should I upgrade it to Ver 3.0 to hopefully end the vicious cycle of death (VCOD, cousin of BSOD).
