Used Intelligolf Eagle 8.3 (The GPS supported version) on Palm T/X no problem whatsoever. Upgraded to Palm Treo 680 smartphone for obvious reason. Experiencing annoying delays with GPS features with Intelligolf.

When tracking distances, once you press "stop" then select the shot type (Drive,fairway 1 or 2, approch, Chip...) there is a delay that can run from 20 to 25 seconds before you get to the other screen. Nerver had this issue with my T/X. Intelligolf support never received similar reports so far.

I'm using Bluetooth GPS HOLUXSLIM 236 SIRF III.

Also using Tom Tom Navigator 5 no problem.
