Re: Navigation System Quirks
There are 2 major issues with the GC Navigation. So lets not get them confused.
1. The location of the antenna. There is a TSB out for this, which involves a new antenna as well as a relocation away from the rasio, I suspect the replacement is solely due to the length of the cable not being susceptible to relocation.
2. The mapping software engine. This has serious bugs, and "appears" to only recognise major highways when calculating routes. This can cause you to be routed 100's of klms away from the direct, or most practical route. Navtaq have apparently developed a fix, which was in testing a few weeks ago when I enquired, and is awaiting a release by Jeep.
