I have the PPC version of this(DELL AXIM30), nothing but disappointment. Not sure if the PalmOS's better.pros: 3d looks fantastic.cons:1)i was going down I-5 toward LA, and the software kept telling me to go back north because it chose to go another route. It didn't correct itself until half way between LA and SF.not to mention small streets.2)require frequent rebooting. it locks up a lot! if you turn off and on the Bluetooth, or turn off/on the PPC, everything need to be reset.Right now i just leave it in the car, not using it. My wife don't trust it at all. what a waste of money.Probably I will try the other brand (software) on this receiver and see if it's better.
