Unit comes with iGO8, you could upgrade to Primo, but it's risky. My suggestion is to update map and leave proggy alone. Your unit is pretty low, so I'm not surprise that it came with iGO8. Try upgrading HERE 2015 and see if it complains. You only have less than 2GB of storage (SD?), so you will have to pick which countries you want to use. Or you might be able to put in 4GB SDHC and get more countries.
