Any Help would be greatly appreciated. I bought a used f90bt off ebay for dirt cheap. the previous owner stated gps just stopped working one day, but it was fully functional otherwise. I thought I couldn't go wrong even if the gps would not work, and bought another gps antenna to try. With both antenna it just sits there flashing yellow searching for signal. Previous owner tried flashing to latest official update, and when I got it I updated to fx3.2 to no avail. I cracked it open, and poked around the gps to make sure the solder joints looked good on antenna connector and all was good. Just a shot in the dark, but would anyone know where to start on what might be wrong, or what I might want to look at. I have an oscope and am proficient at soldering and such. I looked through the service manual that Carver posted up, and did not see much relating to the gps unit. Thank you in advance

Anyone know another forum I might ask?

It's probably going to have to go to Pioneer. Even if you were able to source it to a specific failed chip with a schematic, I doubt you would be able to buy a replacement chip.

Thanks for replying Jason. Quick question what does pioneer usually charge/what am i looking to spend to have this fixed? I know generic question, but lets say worst case scenario the navi board needs replacement. On the parts site it shows $500 just for the part. would I be looking at 500 plus labor?

Also would the navi board be the same in the f700 if I was to find one broken?

thanks again

Yeah, you would be looking at parts+labor. I've heard anywhere from $100 to $300 in labor. I would assume (don't quote me on that) the f700/f900/f90 all share the same navi board, since the only differences between the units related to AV, not navi.

Just a Little update.

I found an F700 with a broken screen for cheap and have done a swap of the navi boards with great success. things that are different are there is not a hookup for the antenna for msn, no digital out, a sticker on top, and on the bottom of the board there is a resistor in a different spot. I did not need to modify anything. dvd works like a champ and gps picked up like it should. Just finished flashing 3.1 with no hiccups and bluetooth update.

Also what are the 2 buttons for on the bottom of the board?
