My maps were corrupted because I had to shut down my computer while the so-called "update" was stuck for three days at 92 hours left. I've been trying to reinstall the maps for five days. MyDrive Connect says the software on my device, which it identifies as a Via 620, is up to date. In fact, it installed a small update just this morning. It also shows a check mark on the TV icon showing that the download of the update to my (Windows 7) PC was successful. I've cleared the cache and redownloaded four times. Each time the download has finished successfully. However, when I try to install the maps to my device, MyDrive Connect shows 0% with 44 minutes to go for about 20 seconds, then says "Sorry, some items weren't updated." I've been through all of the FAQs, watched all of the videos, and tried every suggestion I've come across, but the maps won't install. FWIW, the maps require more space than is available on the device, so I'm trying to install them to the freshly formatted sd card. Please, if someone has figured this out, could you post step-by-step instructions? I really don't want to have to buy another GPS -- this one was working fine before I made the mistake of trying to update it with the most recent map. Thanks. Any help gratefully appreciated.
