Late Model GPS Help

Ladies and Gentlemen,

This is a heads up for late model subie owners with factory GPS headunits.

On a recent trip my factory Harmon Kardon/GPS unit developed a mind of its own and went absolutely nuts,
changing parameters, picking destination points, changing radio settings, and even at times refusing to accept inputs
or even to be turned off.

Once at our destination, some research lead me to believe that a software update on the headunit was required. At Peoria
Subaru, Arizona, it was discovered that my portable Garmin GPS was the cause. Sitting on the dash, the Garmin's power
cord was crossing the display screen of the subie's headunit and inducing an electrical current to the touch screen.
This was the cause of the subie's headunit craziness.

After rerouting the power cord away from the dash touch screen (put a business card in the crease between the dash
vent and the dash and looped the Garmin's power cord around it) there were no more issues.

So, if you have a dash camera, radar detector, or portable GPS, don't allow its power cord to cross the car's touch screen.

Some may ask why I use the Garmin when the car's GPS should be enough. My passenger can input changes into the Garmin while
the car is moving, while the car's GPS will only allow it by voice. And those voice commands take more time, give few
options, and frequently end up going in circles. Add to that ... I have 4 vehicles, and I move the Garmin vehicle to
vehicle as needed. One GPS zoomed in and one zoomed out gives fewer surprises at intersections and exits.
