thanks guys for all the help, and sorry for being a total idiot lol

same prob just came back !

can someone hook me up with the backup files for F900BT my system started failing for no reason. never did any mod or anything so i never backed it up but now those files seem to be my only solution. anyone please help!!!

My F90BT has started doing this as well. I'll be trying out the remedies in this thread. Thanks for the info.

Hi All. New Here, just registered. Sorry for the long first post (I'm a technician)

I have a HATE/LOVE relarionship with my F900BT...Hate it and would love to get my money back!

I'm also having the reboot isue with F900BT.

History: Installed unit April-09 in 2000 4Runner with hardware PBrake bypass and no other mods, worked as well as can be expected (slow and glitchy) until Sept-09 while on a hunting trip. After a couple days bouncing around on gravel roads with GPS on tracking path on unmapped roads, and playng mp3s from a 8Gb SD card the unit started constant reboot when moving, worked ok when parked.

Got home pulled unit returned it to Futureshop where I purchased it in Surrey, BC Canada. They sent it for repair.

Came back upgraded to fw 2.000600 and seemed to work ok for the past year. The glitches were mainly starting on different radio screen then when shut down, often starting SD playback in repeat rather than random and going to map screen after BlueTooth call.

Now: Sept-2010 go hunting for a couple days bouncing on gravel roads with GPS tracking route.playing mp3s from 16Gb SD card, back to the reboot problem. I thought mybe rattling on gravel roads shook something loose. Pulled unit (no longer in warranty) took it apart and unplugged and reconnected all plugs and ribbon cables and looked for bad solder on boards. Didn't see anything suspicious. Reinstalled unit and worked fine in shop. Drove 1/2 block and reboot. Upgraded to fw 2.000800, worked fine in shop, drove 1/2 block and reboot. Found fw 2.000900 on UK Pioneer site (revision list said reboot issue fix in this version) and installed.

This is where I made a troubleshooting error. Thinking maybe the onboard flash memory was full which could possibly cause the OS to lock up as there were 505 track logs saved (I've always had autosave tracklogs enabled) I deleted all the old tracklogs which was a PITA as there is no "delete all tracklogs" option I had to delete each one at a time which took about 20 minutes. Another glitch I've had lately is the track isn't always displayed on the screen (black trail) while travelling about 50% of the time.

Anyway after fw 2.000900 and deleting track logs the unit worked fine on a short test drive but I don't know which action solved the problem as like a dummy I made two changes without testing between.

Since I haven't seen anyone mention deleting tracklogs I don't know if this was the problem. If anyone is experiencing the same issue I would suggest deleting the logs first to see if that is the problem. Maybe the guys deleting the gps files thru testmode are actually erasing the tracklogs without realising it? This would also explain why the units are working fine for several months before having problems as it takes that long to fill the flash memory. I also wonder if the hardware PBrake bypass affects this and is keeping the unit from purging the flash memory? this would make the helpline suggestion about not having the parking brake wired correctly causing the problem an accurate statement...scary. BTW I uploaded the tracklogs to the SD card and checked the filesize on a PC, I think it was about 37MB but don't remember for sure.

Has anyone solved this problem by purchasing and installing the map upgrade with version 3.x firmware? I see there is now 2010 map update available CNSD-200FM available for purcase from Pioneer. Has anyone with reboot issue tried this? Does it solve any other glitches? I would consider the upgrade if the unit is stable and some/all the glitches are fixed. Otherwise my next move may be a hardware mod...2lb ballpeen!

I'll update here if there are any changes as I only did short test drive so far with autosave tracklogs turned off.

GLTA. Steve.

another one bites the dust... i've tried reading through the posts here, but none of them seem to be quite the same as the issue that i'm having, and i'm tryin to get advice on which solution to try first.

I have the f90bt, been installed in the car about a year working fine with no problems, never hacked or modding anything (not super patient when it comes to these kinds of things) not positive about the parking brake thing though

about a week ago, it started doing the boot loop issue, after troubleshooting and experimenting i determined that it only reset once i got the error (don't remember exact wording) but basically it would reset if i got to above 15-20 mph, sitting still the unit would function properly

now, it boots to the splash screen, and then goes blank, and seems like it powers off, just sits on the black screen, no music, no functionality, no side illumination or anything. sat for over 10 mins and still nothing, pressed map button, and nothing gave any type of response.

I can boot into test mode, and i tried deleting the files, and that didn't give me any type of fix, still goes to the black screen, i also tried the "eject trick" and that causes the unit to just sit on the splash screen

so now i'm stuck and just kinda frustrated

yes you did it wrong. put the card in and hit reset or turn the car on. you don't have to hit any other buttons.

hey can u assist me i have a fatal application error my system keeps on rebooting and wont work can you help me please step by step i am streesed out over this i have the f900bt i dont know where to start

Deleting the gpspara files used to work for me - just this week it went into reboot but it was a difficult and more nasty kind of reboot loop. It was so nasty I couldn't even get into test mode - I ended up having to "upgrade" WinCE (in reality, just overwrite it) with a format to clear the entire unit, then copy my backup over. I think I'm going to have to keep a SD card now with both the WinCE image and my entire backup with me on the car at all times. What a PITA. Wonder if the new pioneer units are still so "reliable"...

I am having the same issues as everyone else with the F900. I swear pioneer has sent out a signal that crashed our radios. For the same problem to affect everyone almost at the same time. Anyway, I am asking anyone if they have a test mode file for the F900 they can provide. I have read all 12 pages of post and would like to try the gps file deletions method, but I first need to get into test mode. I wiped my sd card clean and loaded a version of test mode on it, turn the key to the on position and I then get an error every time. What could I be doing wrong. I have had this radio for over 3 years and then all of a sudden. I was playing music for the sd card when all this ish happened. Please help if you can. (By the way, it reboots every time when I go over 20 mph)

They have a video on youtube on how to do the fix. The only difference was at the end you were told to hit the reset button...http://www.youtube.com/watch?v=Y4hP1t1mhuM

Ok so I won't be able to test the parking brake theory until Wednesday afternoon but anyone else having the problem feel free to give it a shot and post your results!!

so was the parking brake wire the problem....ive also bypassed it to the ground and after a few months it started to reboot on me..ive switched the unit 3 times already and still the same problem

Mine did the same thing about a month ago, sent to be serviced/repaired. The tech there replaced the main control unit (around $450 for the part) that fixed the problem completely. I was not happy with the f700 anymore (mainly due to the gps) and I work for best buy so I just called the tech again and got him to give me an order to get a new unit. If you guys want I can try to find the repair order and find the part number for the part used.

I had the same problem. My Fix:

- upgraded the firmware to 2.00008 thats the latest one from pioneer website.

- upgreaded bluetooth.

- find the testmode software, put it on sd card and start ur f900bt.

- delete these files: gpspara0,1,2,3 and also delete the userdata folder ( this will delete ur custom start screen - back it up)

Reset the unit using the little reset button and done. That fixed my issue.

PLEASE, for the love of GOD. help me figure this crap out... I have downloaded the newest version off of pioneers website trying to fix my reboot issue. It worked for like 3 minutes and then is doing the same again whenever I am driving over a certain speed of like 15 to 20 mph. I keep reading about how to download the testmode files and delete the gps1,2,3 files and all that sounds fine. But I cant seem to get the test mode files downloaded. I have tried using my personel desk top comp, and a buddies laptop and still when It says its downloaded, it wont let me open the file. I just want my freaking stereo to work again. It worked fine for over a year and all of a sudden decided to go on strike... Please help

BHarper, I have the files that will let you boot into windows up to v3.0. pm me your email address...
