Just had to comment about the N2 navigation --- it is fantastic!! I had a piece of junk handheld that was totally worthless. I chose the Pioneer based on some reviews and postings, but I can't believe how good and useful it actually is.
Very shortly into a road trip to Louisiana, The Navigator closed her road atlas and said, "I have been replaced..." (Unfortunately. she now spends her time watching speed limit signs and reminding me to slow down 
)
