Great Alternative to Pricey Standalone GPS units

I bought this for my old Dell Axim X3i, it works great as a GPS for both driving and flying. I didn't try the Ostia software that came with it, as it can be used in conjuction with the more popular TomTom or iGuidance software. Although I haven't personally tried the Ostia software, I read a couple negative things about it and opted to check out the alternatives first. It is very accurate and has a quick refresh rate with TomTom. The PDA holder is a little clunky and comes with barebones instructions, but it is a welcomed extra. It comes with a cigarette lighter adapter, but the wall adapter from my PDA also works.
