Yes. If you are familiar with mobile audio installation, this is a very easy and cheap DIY project. You need to put a switch on the speed sensor wire and cut the parking brake wire to the head unit. Get a hold of the service manual to see which wires.texastom5 wrote:Is there a way to enable full use (such as when the vehicle is completely stopped) of the nav system when the car is being driven so that my passenger could access all the info/capabilities? Thanks.
IMO, there is no need for a DPDT switch. The E-brake wire serves no other purpose going to the HU.Timmbo wrote:The other options is to install a Double Pole, Double Throw Switch (DPDT, available at Radio Shack) in between the VSS wire and the E-Brake wire going to the stereo head unit (AV Control Unit). This will allow you to use all Nav functions at the flip of a switch.
Lets put it this way.....terrycs wrote:

It is easier to just cut it and use a 2 position switch on the VSS wire which essentially toggles between full access (nav updates off) and normal nav use.
