Sandi, thanks for your post. I had similar issues and additional ones such as not being able to find an address to a location less than five miles away (the Moth Man Museum in WV) and being unable to access GPX files from the additional SD card. I’m the 2nd owner on a then “nearly new” NAV VI and I checked with Garmin to determine if Warranty was transferable. It was! They had my personal info & serial number (based on my phone #) from the re-registration of the unit.
I received the authorizing RMA within minutes of my conversation with “Levi” who explained that there was a known problem, the”Ghost Issue Touch”, which may have been caused by some dust or almost microscopic debris on the touch screen panel during manufacture from their Taiwan facility as well as other software coding. He also suggested that I remove the battery from the unit before returning to keep as a spare! I’m sure battery replacement costs follow the BMW credo of Bring More Wampum! 🙂
