I have a VIA1515TM that didn't update properly. Now it won't connect.
After trying to update my Via1515TM, it briefly showed some navcore.dll or something to that effect and it proceeded. But since then, I can't connect again to do updates; MyDrive says device isn't responding, even though each time I plug it in and unplug it, the computer has the beep tones that it detected the USB cable being plugged in. Is there a way to remove the current map and reset the firmware/OS of the GPS to the way it was from the factory and then update the map file? I noticed that I can remove the map file and some voices, but nothing that looks like navcore or anything system-like. A few times it did show "connected" and when I went to update QuickGPSFix, it says "getting ready" but it never proceeds beyond that no matter how long it's plugged in. In the past, a QuickGPSFix would take less than a minute. Thanks very much!
