my gps has really been slow and not accurate with 3.0. It froze the other day trying to route directions and stayed like that for about 4 hours. Then i opened it back up today and it was still frozen but finally loaded after about 3 minutes. Then when i am driving it takes forever to load my location, for instance it will freeze on a spot and then a few hundred yards it will appear back to where i am. is anyone having this problem!
