ive got a dell axim x30(high) and an iBlue-737. earthcomber works great on its own as far as maps and such, but when i try to use the gps, it will connect, find my position, refresh about 2 times (very slowly), and then do nothing for about 2 min, then say "lost communication with gps device. please check connection and restart gps." i can then reconnect no problem, but get the exact same situation again. it happens every time whether im moving or stationary. anybody have any thoughts????? am i missing something??
