I finally got navigation system. Online costco had it for $249 - total with tax and shipping came out to $280. This nav system is small, light and very portable. It also has bluetooth. i'm not too sure if i'll be keeping this and have to test it out a bit more. I could not understand why the satellite could not detect me in a couple of instances. It was because i didn't have the antenna up. duh. on another occasion, it got stuck and i had to reset it. i'm somewhat indifferent so far. bluetooth function is nice especially with the new ca law going in to effect this summer. sounds ok and speakerphone is loud enough. restaurant lists restaurants closest to your current location (you know nothing else except the type of food it is), unless you know of any in particular that you can type in and sometimes it takes a while to find it on the system.
Update as of 2/29/08-I returned this item. Bluetooth was splotchy and people on the other end always complained of bad phone connection. I imagine this has something to do with where the GPS is placed in your car and where the speaker is located. I went to hawaii big island and tested it out. right out of the airport, i tested it to find the nearest costco which is less than 5 miles away from the Kona airport. it only listed all the costco's except the one nearest. I was disappointed. I know that costco has been there for more than 8 years, so why was it inaccurate? of course, if you were unfamiliar with an area, you put all your trust in the gps and assume it will direct you the best route to where you want to go.
