Hi. I have bought a yakumo gps. Which is like a piece of s... But think it comes to the developer. Who is also full of s... The gps i bought is 300mhz. But that is way yo low to update the display fast enough and run program with an acceptable speed. So is it possible getting a gps that rum 800mhz or more ? And it must run windows mobile. Plz. answer with some links.
