Re: Navigation System Quirks
Well, the latest verion of that software is 2.136, so if they did install 2.126, they are still well behind the current releases. You may have had 2.136 and it would have been overwritten by 2.126.
Best you go to Sox's site, download and install 2.136 version. It won't fix Routing, but will enhance the radio performance.
The dealers have a tendency to not think about what they are doing, and simply install software, even though it is an earlier version.
