curious you would think the 28 pin is hard to find; I got mine off a fleabay vendor. the usb cable and satellite radio antenna on the other hand I have absolutely no luck whatsoever. For GPS I used GPS Antenna for ECLIPSE AVN726E AVN5533 AVN5435 AVN30D. The common Motorola antenna adapter won't work with the F10. I had to get the adapter of a Toyota/Lexus.
