Permanent Docking Kit -
Get perfect sound via your car’s speakers! Do you want to install TomTom GO using your car power and car speakers? Now you can with the permanent docking kit for TomTom GO.
Looks like it comes with a docking shoe that can be mounted just about anywhere. I like the idea of having the audio come thru the stereo speakers.
