After getting lost this weekend and my wife and I screaming at each other over who's fault it was (hers) I have decided I need a GPS system for my pda. I currently have the TX and wonder what is the best system out there for Palm? bluetooth or wired? I also own a 2000 Chevy venture that has a reflective coating that will not allow my handheld extrex gps to work on the front dash. What ever solution I have needs to have a longer cord to run to the side windows or rear windows or use bluetooth. I would be willing to switch pdas to a PPC if opinions think the ppc would be better for GPS systems. I have heard of a few systems , namely TOM TOM, co pilot, garmin systems. What do you guys think?
