I loaded tiles from the Inland Lakes map into the internal memory of my Dakota 10 using Basecamp (after splitting the img file via GMAPTOOL) and now I have a brick. I've tried forcing it into USB Mass Storage Mode using both recovery methods in the Oregon Wiki at least a hundred times to no avail - I can't get my computer to recognize the device and the unit just continues showing the Garmin logo ad infinitum. Anything else I can try before sending it to Garmin for repair?
