I have a 6 year old garmin unit that I really like. I also have a Tomtom and definitely prefer the garmin. Better maps and speed limits show up on the roads that I drive on. I don't always see the speed limit signs and its a handy feature. If you can afford the lifetime updates that's what I wish I would have gone with.My sister and brother both have navigation units and its pretty handy, so I'm thinking about getting one. I think they both have Tomtoms, should I go for that or do you have any suggestions?
Old thread. This is very true but my smart phone forces the screen to ON when in GPS mode and runs the battery down quickly. Works fine though if you can plug it in to charge while driving.if you have a smart phone i guarentee it has gps and you can hook it up to your prius with the ipod jack and hear it thru the speakers. so save your money..???
