Rather than paying $80 to 100 for a new GPS receiver, I am going to try using my Earthmate GPS. My question is this....The Earthmate has a USB connection, but the BCD996XT has a serial port. I am thinking of building a cable to connect the two, with a female serial port and a female USB. Looking at the pictures of the Uniden GPS it shows a cigarette lighter plug in to power the GPS. So, with a straight null modem cable will it work? Do all the GPS's that are approved for this radio have a separate power connection? Great radios, I bought one for the shop and one for the truck (ebay specials). Took a while to figure out how to program it, but it has been a success.
