Hi I have a palmone tungsten2 pda withtomtom navigator 5 and I like it.The all have quirks and draw backs but I like the pda because they give you cds to down load or a 1 gig card preloaded. If the unit breaks you still have all the maps and bluetooth gps unit.Also wanted one I could take to Europe and walk around the streets to find poi's. Goodluck
