I see so many new models available on the market - from Garmin nuvi to garmin C330 c340 seems to announce street names c530 does not announce street names, but it is newer, acquires satellite signal better and has a non-glare screen there's Tom Tom One that some people say is great there are some Magellan models - they provide GPS devices to Hertz and the one I used in a Hertz car seemed to be working fine.
Can someone help figure out what is really the best portal GPS out there? I plan to only use it in my car.
Thanks.
