OK got this Gps 50lm for about a year and half its been real good now after updates it wont's to take me on nothing but back roads and side street. it does not matter what i put in it tells me to take nothing but U.S. highway or state roads no interstate its not the avoidances all of them are turn off i even try to switch the route preference faster time or shorter distance its almost the same directions the only differance is the faster time does take me to the interstate but only for a very very short distance then it gets me back on some backroads so what is causing this issue and is there any other people have dealt with this or is this a problem that garmin needs to address or do i need simply need to upgrade to higher end model
