I found that the Panasonic Strada CN-GP50U GPS System has a 5 inch screen, but I’m looking for larger than that. It’s also important that it’s not bulky. Any suggestions?

In other words, are there any GPS Navigation systems that don’t just use the pre-entered maps? How does that work?

Are these the same? Im looking for a GPS thingy but I cant tell if these two are the same. Also, which one is best to use. I need a compact one to use in the car and to carry around. My preferences: accuracy, easy updateable maps.

What GPS system would you reccomend for a car, money being no object?

I have Camry , Looking for a gps system which is reliable and very accurate.
If you have any good suggestions I appreciate your answer.
Thanks.
