How to update Garmin Map To 2018 for free Latest update Garmin GPS Road Maps for Free America 2017 How to Set My Business.
My problem was that apparently the unit originally came with 2008 maps. Somehow during the auto-upgrade it appears the transfer may have been interrupted and restarted or something (supposition only). Anyway, the 2009 maps were installed as supplemental ones with the 2008s staying as the main ones.
Unlock code was fine for the 2009s but was overwritten for the 2008s. The original maps were what was giving the error and I could still use the maps because the 2009s were unlocked. As per direction of 'James' at Garmin, I deleted both the gmapprom.img and gmapsupp.img files from the unit. Reinstalled all maps with Mapinstall (these were named as gmapsupp.img); renamed the gmapsupp file to gmapprom and voila!
No errors and I have more space free on the unit!
How To Fix A Garmin Gps that Opens and Stays Frozen on the Start Screen The purpose of this maneuver is to be able to enter the USB storage mode. From there, you will be able to delete (or modify) what is problematic. Start by renaming some files. First of all, make a backup copy on your computer. If these maneuvers do not solve the problem or you have formatted your device in NTFS, try formatting the disk in FAT or FAT32 format.
You can recover most of the missing files with the webupdater software. Some devices will not start if they have no more files. Ask one of your friends with an identical model to lend you his GPS so you can copy his content to yours. Remove the GPS safely.
