I imagine that a few out there reading this have experienced what I am about to say.
I was excited when the new nav came out called Primo and I was looking forward to downloading and installing the program. I didn't have any problems that many of you are now experiencing. That's why I uploaded the Primo from my device so you could just download and install and pretty much get it working "out of the box." Also, my upload contained the TTS folder that I uploaded with all the modified English-speaking voices for WinCE 5.0.
Now for my experience: When I first tried Primo, it had me making a right turn on a street when a left turn was called for. I know this because it was in my neighborhood. At first I thought it was the mapset I was using. I was using Navteq Q1 2009 NA so I changed to the next mapset - Navteq Q2 2009 NA and the result was the same. I changed again to the new TA maps for NA and again the same result. Now I just changed to Navteq 2010 NA maps and the same result. So, it's not the mapset!
Here's what happened with all of them. It had me making a right turn at the next block called Plymouth Ave. when it should have had me making a left turn on 2nd St. I wanted to see where it would lead me so I made that right turn on Plymouth and it made another right turn on Second St. where the left turn should have been made to begin with. After that it was fine. But it did take me out of the way. Incidentally, I tried the same route with iGO 8.3 and Amigo and they were both perfect. So it's iGO and Amigo for me. Hope they get Primo sorted out.
Any of this sound familiar?
