Would it be possible to put tt maps in this device and if so would i be able to do it via navitotal.com
Sorry for being a noob again.

These devices is special and support for these is very difficult.
some WinCE Garmin mobile XT and tomtom navigator release maybe works, but usualy you must test it by self if you are lycky here is some person who own same device and get it work and give help to you

Ok thanks I will wait for more advice.

Could I run it with iGo maps as I hear good reports of these maps.

iGO runs on most devices, but i would still research the device fully before purchase.
