another point... I have purchased and refurbished eleven nuvi 2595 for friends and family (preowned units can be purchased by $25 plus $10 a new battery and perhaps $3 for a suction cup - traffic charging wires are very expensive, so only purchase LMT units with wire - currently I adapt the wire for pluggin into USB ports in the cars - must be 2Amp) Nuvis and garmin (up to date) maps are much more reliable and precise in routing than google maps or whatever.
All in all, family and friends are happy. And updating them is very easy cloning device to device...
