What are your settings in Tom Tom. From my reading on the net, you would need to select other cabled nmea GPS and then the bluetooth card(or the equivalent com port). But as I don't have any GPS myself that is only hearsay. And I hear TomTom is very picky about the GPS input.
The biggest problem I have with a CF GPS is that it takes out one expansion slot. And the other one (SD) has a lot of controversy over whether it can take over 1 gig. I went safe and only bought 1 gb SD cards, but that might hurt me when I'm using moving maps software, and my CF is taken. The Hiacom GPS with the SD expansion slot looks tempting (305III) but I'm wondering whether it would have the same issues as the Sandisk one. Also I haven't heard much positive on the durability of them, as per post #3. I think I'll end up with either the Holux or GlobalSat CF as both of them get glowing reviews everywhere I've seen.
BTW, does the external antenna for the GlobalSat have a magnetic base? And if so could the magnet be removed?? As I'll be using it in a helicopter there is no steel in the cockpit, and the magnet could mess with my compass. Just going to velcro it down. Thanks for all the help.
