That device is too old, 7 years, dont expect from it miracle... It's only 64MB, if know that OS load part of it, not good idea iGO Primo to use on it, iGO8 is better option, iGO Primo will work if not much stuff inside, like 3d, much pois, speedcam, and if you have at least 32MB free, and you'll need iGO Primo PDA version, optimized for WM-PDA, cause of memory division function problem. Look in iGO software section, and look for iGO Primo pda fix, usually in iGO PRimo releases, always inside is packed PDA-fix Primo.exe, just use that exe.
