I have the f90bt for the past 3 yrs now. All of a sudden on Sunday it had an error window saying not enough memory. I pressed on the reset button and now it constantly reboots itself. Cant listen to the radio etc. It constantly has the "system startup in progress. Please wait" message. It has the 3.020100 version and 02.000400 version for the map. Anyone else had the same issues? Is there a fix to this? I called pioneer and was told to ship the unit to them to get it fixed for $230...

Yeah you got the reboot issue. Do you still have your SD card with 3.00201 firmware update on it?

Yes, I do...but when I try to insert any of of the SD cards it doesnt do anything. It still just constantly reboots.

You need to follow my Pinned thread basic reboot loop fix. Except you need to use the 3.0 files with daftias mods instead of 2.0 when you follow the directions.
