Your best bet is here for info on those types of devices http://www.gpspassion.com/forumsen/default.asp?CAT_ID=2 It can be done, where you can get to the desktop and mod the files. SNO
So I picked up this Pyle device, which runs WinCE and iGo Primo. I'm wondering whether anyone has tried to hack these WinCE devices. I feel like there is a lot of potential - Web browser, better video player, better iPod connectivity, etc. - but I'm not sure how to get into its filesystem and start modding the built-in menu.
Currently, all I have access to is the GPS SD card, and a way to set the path to it in the system menu. I am thinking maybe I can run an alternative front-end by doing so by running the "navi" icon which would drop me into an alternate shell over which I would have full control - or maybe there is an easier way?
Any suggestions welcome.
