I've been having intermittent Sync and screen problems the past month or so. I did a master reset and it made the screen move faster and eliminated some but not all of the issues. It still randomly tunes to AM or FM instead of the last Sirius channel I was tuned to. Also my number of preset pages and display backgrounds defaults to the standard settings. Also, sometimes the automatic updates gets turned off and Navigation history gets deleted. The worst thing that stopped happening after reset was the map only loading on the bottom half of the screen while the top half was blank. Hopefully this latest update will fixes these things and doesn't mess up other things.
