That receiver should work with Garmin Mobile PC. It is NMEA compliant. I use an NMEA receiver with my version of GMPC.
GlobalSat Bu-353 Receiver. Brand New in Box.
I bought this for use with garmin mobile pc but after i received it, I learned that it doesn't work with locked maps for Garmin. I don't want money for this just want a Garmin GPS in Return.
