I always look things up in Consumer Reports mag. because they check things out....of the top three GPS systems they do recommend the "Garmin Nuvi 300" for $500...they said it has a super easy touch screen & for $50 more the nuvi 360 has Bluetooth hands-free cell phone control. To make a call, dial on screen numbers, to answer a call, tap the screen & speak through a microphone.
The other two they recommend are "Tom Tom One" for their bargain buy at $300 & the other one is "Tom Tom go 510" for $400.
Hope one works foe you
