I know some of you prius owners are looking for a portable GPS . I found info on a new GPS coming out soon. one thing I want was a big screen and this one has a 7" screen. Also with a optional sensor you can get traffic and accident warnings. The price is around $1100.00 that is cheap compared to the built-in toyota GPS. here is the link: http://www.gpscity.com/item-garmin-streetp...stem/sp7200.htm If anyone has any other info please post it here. Thanks DON
