The Tom Tom -XL-S GPS I purchased from Walmart was fun to nagivate with - you know it talks to you in a voice of your preference as well as tracking your path and speed on the Highway.  When the battery went dead however it would not recharge so I had to exchange it for another... the very next day.  The new one has not been a problem in any way.  I managed to connect it to the internet and update the maps and information very easily.  We really like it.
