I've tried every instruction mentioning how to bring up the 'over-ride' list in the gps section, but still nothing works. I have the 3rd gen nav unit, but most of the mentions are for 2004 on. Most of the posts mention tapping the left top, then left bottom in the gps section twice, then the right bottom corner, but I couldn't get it to work. My reasoning for wanting to do this is that its should enable me to view my battery output, and a few other gauges.
