Do You Know the Way to San Jose?

Well, San Diego actually. We will be packing up the car and leaving good ole’ NorCal in a couple of weeks for Kevin Sharp and Debbie Glazner’s wedding mid-April. For the road trip, I’m considering buying a GPS unit which I think might help other than just driving directions. Sure, one can go to Mapquest or Google Maps and map out the directions, but I think the selling point of the GPS is the Points of Interest (POI). If we’re on the road and need to stop for gas or take a break, the POI feature can help locate restaurants, gas stations, attractions, etc. I think it would help us make our trip somewhat stress free. Anybody out there have any thoughts?
