I was able to get a copy of iGo8 maps and here are the differences I noticed between Primo maps. iGo8 - loads faster, less detailed compared to Primo, no TTS voice, no junction view, less options, no detour options when stopped, faster reroute probably due to faster loading Primo - loads slow, very detailed with POI, TTS voice, junction view, a lot more options and customization, has a detour prompt that pops up when you are stopped if the road ahead is congested, slow rerouting, if you take an exit off your route it will give you POIs that it thinks you are exiting such as gas stations or restaurants. Also one thing I do like about Primo is that if you have TTS set, when you go over the speed limit it will tell you what the speed limit is and tell you to slow down. iGo8 will just say you are over the speed limit. Overall I like the details of Primo but iGo8 is much faster with maps and loading. I will be testing out a few more map programs in the later weeks such as TomTom, Garmin and Sygic Maps.
