For those of you who have been reading here at navitotal.com for awhile now you know my personal experiences with Primo and the navigation problems that I have encountered. Recently I upgraded to v.1.1 and today was the first time that I had a chance to try it on the street navigating the same route that I tried with an earlier version. Before with the earlier version I would rate it at 97%. The Primo people have definitely improved v 1.1 and now I would rate it at 99%. Still needs some work but vastly improved.
Conclusion: I would recommend Primo v 1.1 without a doubt. But iGO 8.3 is still a drop ahead in my book.
