On a wince5 unit I had, igo8.35, Primo 1.2, Primo 2.0, Sygic, Navman, Garmin, Tom Tom, and Route 66.
Got a Win ce6 unit now. TT wont work on CE6 anyway but Ive only got Primo 22.214.171.1244557 (i3) on it now.
I used to use multiple maps but just only use NT maps on it (19.1 atm)
So only one Nav sys now. Primo P2. with diMkaWA_P156 skin.
great forum, have had various sat nav programmes on one device.i had igo8, amigo primo1.2 and memory map and this now settled on primo 2 .It works great ,i like the graphics, it makes looking at the screen pleasent.Im using a 5" unit , with 4gb internal space and 128mb ram, so have no problem running any sat nav programme so far!
