So, I got this double Din radio/GPS unit, must be a chinese thingy, it runs iGo I guess.. I was wondering if there was a way to update the maps or iGo primo or whatever, not even sure what is what, program or map file,, bo?? and it crashes sometimes during navigation but will not crash if I keep it on turn by turn selection.

I know I probably not in the right place but I am super new at this and I am sorry,, would really appreciate some help or direction.. thx all
