I think you're confused. Neither the i500 or i600 (MS Smartphone device) have an embedded GPS chip in them... the only Palm OS devices with builtin GPS are the Garmin iQue series... and they don't emit NMEA - they have specific API's to retrieve the data (from which you could build a NMEA string if needed).
The NMEA protocol is extremely well documented... Google is your friend... Luc has already highlighted some good starting points. Gavin. -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
