After the turning on all by itself thing started happening. I noticed it needed to be charged. So I hooked up to my pc for charging. Then opened up tomtom home and it had a bunch up updates. It updated and I thought all was well. I started scrolling through my device and found that all my previous information was gone. All my favorites (about 30 destinations) are gone and half my symbols are grayed out. Now I have to re input everything. Did something in the updates do this?
