Since the original update that gave me summon I have had 4 additional software updates. Each shows the same release notes starting with info about summon. Each says my summon settings will be erased and I will have to reset them. I check and nothing has changed(and yes I do have some customized settings in there). As best I can tell the only thing that has changed is that the radio is off when I get in the car in the mornings and I have to reselect the same station I always listen to. My auto piloy continues to be whimsical about whether it is going to follow the lanes in town on the route I travel (interstate) every day. Same time, dry weather sunshine, sometimes it follows the lane, sometimes it goes in the other lane (of course I stop it, I let it go until it begins to cross the line) and sometimes it tries to hit the divider. Does anybody know what these subsequent updates do?
