I believe it has to do with the booting... I believe it may have fried to the point that it cant read the internal memory to boot into anything but bios... I am taking apart mine now to see if i can find where the internal memory is stored.

Unfortunately no. The unit will not turn on the screen unless in diagnostic mode and freezes when trying to write the wince image. And if trying to start normally or boot into testmode off the SD it will again display the lights on for ten seconds or so (no screen activity. not even splash). then lights turn back off and the fan continues to run in the back. but thanks for the attempt

Ah. Thanks Warhawk. I am at work and cant see the dissasembly photos here but i will check when i get home. I was just thinking about taking it apart and seeing what i can find there for where the internal memory is stored. I hope its not on a onboard chip... but if it is not much i can do about it. And i checked the link for that pac parts and nothing interior to the unit for the avicf90bt but thanks for the link. But i will look into the dissasembly photos when I get home and as always thanks again Josh

And can you think of anyway to replace this built in drive? besides replacing the entire unit lol. or anyway to repair the bad blocks

Does anyone have the two f900bt US working winceimg. Original or modified.... Anything that works on the f900bt us

So Im at a complete loss.... Just about to give up on this thing.... I have tried to see if mayb my wince img is corrupt mayb. Anyone know where to find an original f900bt US wince img would be.... I have tried the one from the pioneer 2.08 update from there website and the one from the 3.1 fx update...

Cajun Thanks for the response but this is what i have been trying. just the two files mentioned are on the two cards that i have been trying and the same ones i used when originally doing the upgrade to 3.0. Just always getting stuck on the read 100% screen. so annoying. Im going to try to find yet another sd card of some sort and see if it will help. I really doubt it as these are the two that i had no problem with before.... So I just tried a 3rd memory card and same issue.... Can read but gets no further

I have tried the winCE files from the 3.1 download and also the wince images from when i did the 2.08 to 3.0 update and both freeze on me. I have tried 2 different sd cards and have reformatted them both with a full format not just a quick and tried again. These are the same 2 cards i originally did the update with also. But it gets to read 100% then freezes when i do the update wince with update. I can get it to go to read 100% then write 5% and then freeze when going to update wince without format... Thanks for the response and any other ideas Josh

I apologize if this has been covered. I have read through the 57 pages here and the 28 pages on the 3.1 fx update also but may have over looked something. My f900BT US is just reached about a year and half old and stopped working on me. It was factory shipped 2.06 firmware and I did the legit 2.08 update from pioneer website. Back in march/april of 2010 I updated to the 3.0 update from files from here. Then I updated to 3.01 legit update from the pioneer website again. I have had no problems with any of those updates and all went flawlessly with no issues. I have done no other modification

I have had my Avic F900BT for about 2 years now. I got it when it first came out and have done the updates to the 3.0 download from a member here and then official update from the 3.0 to 3.1 or whatever the version was. I did this update back in about March so at least 5 months ago. I never have had a problem with it except a few places I believe the GPS would cause a reboot as one road the same spot would cause a reboot. But no other problems to note. I drove to work yesterday with no issue and parked. When I went to lunch the unit will not boot up anymore. It will display the lights on

I am also having the same problem. I went to work with it working fine. Then when i went to lunch it would not boot. Just the white lights come on for about 5 sec then shut off. I pulled it out and confirmed the ground, power, and ACC or still working properly and the fuse in the back of the radio is not blown. I don't know what to do with it either but is out of warranty now and have no clue why it's behaving this way

Will a DVD still play? Did you have the parking brake bypassed before? It almost sounds like the features you are trying to get into are the ones locked out when the unit is not in parking brake mode.

Yes I have, and it's NOT going to work right! The way the inputs work for the ipod and USB functionality you need to use AV1 which is in the rear, if you use the front with the RM10, then you won't get the USB control off the head unit since when you want to listen you're on AV2, but the controls are over on AV1. You're making this way harder then it has to be, read the install sheet, do it correctly, and you'll be glad you did, the combo you want to use is a hack and won't work right. DianeBrat is absolutely 100% correct. if you put the stereo into ipod mode it recieves audio/vid

I agree that i dont think you are using the right cable. the right cable should have an ipod connection on one end and about 6 feet of red white yellow rca on the other as well as like a 6 inch usb to plug into the usb that is built into the stereo. The red white yellow plug into the the av1 input of the radio

I have actually done this feat before. The way i did it was to just use a relay with a toggle switch. have the relay be activated with the toggle switch. when the toggle switch is not activated have it provide power to rear camera. When you flip the switch have the relay provide the power to the front camera. would just also need a rca 2 to one adapter.
