I got it working. Not sure what happened, files may have been corrupted? I wiped my device and SD card. I removed the SD card and re-installed OEM Navcore from TThome, and rebooted, and then updated the TThome Navcore (up to 9.510 for Go 730). Installed map to SD card, used Fastactivate...done. Had some trouble with Loquendo computer voices (Susan is my favorite)...Over-wrote the Loquendo files on the root (internal) memory with backed up version. Re-ran TThome, and got all my mapshare updates.
