Hello, I get lost. I have no sense of directions. I need a GPS system. But before I plunge myself $100-$300 down the hole for a GPS system, how well do they work with a Pocket PC (h4155 in my case)? I've seen GPS systems in action in new Lexus vehicles or rentacars, and they're awesome... accurate and real-time... i make a left, and the darn thing shows me making a left turn. If the GPS systems coupled with a PPC gives the same kind of performance, I'm sold. But I'm afraid that, like all handheld versions of anything, the performance will be not up-to-par with their non-handheld counterparts (e.g. Windows, Outlook, MP3 Player, Digital Camera, etc.). Opinions, anyone? Thanks.
