FF,
Sunday's hit the nail on the head, the GNS430 using the external fuse mounted antenna will be able to keep more sats in its sights, the small antennas on PDA and handhels GPS's aint man enough for the task, i belive that they may not be able to receive the same amount of sat's as the GNS430 can. ill need to look into that one.
Or maybe the Wobbble is back on????
Stu,
