I have a Garmin 650 GPS. Instead of plugging it into the 12V recepticle I was thinking about adding a aux pwr port on the top of the dash. It would be connected to 12VDC and look very similar to the MP3 connector. I would cut the GPS pwr cord shorter and change to connector end to match the pwr port. I use a beanbag mount to place it on the dash.
Any thoughts on this?
I don't have my smartie yet but will before xmas (DDE says so and it's never wrong!)
