I recently updated my Map for North America and ever since it doesn't operate properly or give accurate information, i.e., often reflects unpaved roads when they have been paved for years; whenever I'm around a residential area with 35 mph or better speed limits, the system reflects only a 25 mph etc. I called my local Mazda service center and they had me check my system versions which are:
- OS Version is 70.00.352 NA N
- Music Database Version is 00.09.000
- Fail-Save Version is 70.00.352

They told me the issue has to do with an "out-of-date" radio version and that I had to come in for an update which will cost well over $100.

Does anyone have any knowledge or experience with this issue and, if yes, what did you do to solve the issue?
