ok so I just got back from a trip from Louisiana to Boston. this navi is new to me and this was my first big trip using it. couple things I noticed. My clock on the gps screen went haywire somewhere in tenn. it was off by like four hours. however when i switched back to the sirius mode that clock was correct. any ideas? also is there a " I'm stopping for gas,food,bathroom, etc button so stop friggin telling me to turn around button?" like pause navigation or something? other than that just some new maps would be great bunch of places where it was telling me exits that don't exist or merges that are not there

Maps on these things are very outdated so you will get some erroneous direction once in a while. TN seems to be pretty bad about that. My last trip through TN, while I was going through Knoxville, it took me off the highway through downtown just to direct me back to the highway again.
