How can I safely remove the Curtis pre-installed maps & navigation software safely so I can free up space?
First make sure that you have installed another complete navigation software, e.g. iGo + iGo maps, and linked up to it successfully. Then, with your GPS attached to your computer, find the “map” folder on the resident flash of your Curtis and delete that directory. WARNING: If for any reason your replacement software and maps fail on you, you’re left without the backup of the Sygic maps. An alternative could be to just purchase a higher capacity SDHC card and make the 2GB’s of Sygic related software less relevant.
