The unit works fine but every 10 minutes or so the screen goes blank, then the message "updating GPS firmware 1%" comes up. It takes about 10 seconds to update to 100%, then shows "GPS firmware update complete" before resuming normal function.
This isn't normal is it?

there is actually a problem lots of people have with this unit and it seems in the FAQ i can find through garmin that it can take up to 30 minutes to aquire the satellites. there is no fix but if it has the option to get a additional antenna i would try so. If not id suggest a new unit.
Have you tried updating the firmware? A new version is available from the Pioneer website. You will need a blank, formatted SD card. Unzip the files from the Pioneer download and copy to the SD card. With the key out of the ignition put the SD card into the unit. Put the key in the ignition and turn to position I to turn on the F700BT. The update takes around 10-15 minutes. Ensure that no unnecessary electrical accessories are on in order to save battery life.
I have the same problem. The unit works until I connect it to whatever computer via USB (Mac or PC). The screen blanks out as soon as I plug in the USB cable. I have to disconnect the device and only then I am able to turn it on again. That started after Firmware update from V 2.90 to 3.00 . I am not sure this is causing problem. What about the firmware versions of your devices ? Are they all on the latest ?
However, does anybody know if there is a way to go back to firmware version 2.9 if it is not possible anymore to connect the device to any computer (evtl. through putting data on the microSD card ?).
