Soniq ONR350; 50MB FRAM + 128MB/256MB SD card. OS WinCE 5.0.0 processor ARM v4
map viewer Destinator 6.x Existing AU map 2006.xx.4262.
Cannot mount SD card in puppy linux, which can read almost any std format. Do not have user manual, but do have win 98, win XP, win7 win10 A special programme was needed to load maps from other gps, but can't remember name or source. This is a nice unit, and I'd like to keep using it, but new maps are essential. any s'ware upgrade avail would be much appreciated, with info on how to upload.
winCE6 looks too big to fit in my avail RAM? What do I do to remove Destinator and install free navigator v??? and AU maps, pls? I do not know the max readable card size for this, pls advise.
