Possible solution to Nav Override

[TheSweenyFiles]

this may have already been discussed but i was messing around on the forums and came across this.

http://www.toyota-4runner.org/audio-electronics/41632-5th-gen-navigation-wiring-info.html

In this Diagram, section R9 #3 is labeled as "sense speed" could this be a wire that senses if the car is moving over 5mph to disable the nav functionality?

if it is, do you think it would just need to be cut. or would it maybe have to be grounded?

...or is the nav functionality driven off of the gps signal to determine if the car is moving?

anyways,
let me know what your thoughts are!

Edit: Or am i just an idiot and this is for the volume that can be set to change with the speed?

I am not positive this applies to our OEM Navigation units, but this was in a post from a guy with a 2006 4Runner:

From what I recall on the OEM nav:
The OEM Toyota nav from what I've read cannot. IIRC, there isn't really a permanent bypass (unless we're talking about CoastalTech or VAIS Tech kits) for Toyota nav's. One way to do the bypass is to cut the VSS (vehicle speed sensor) wire which activates the lockout when you start moving. However, Toyota navs also rely on the GPS antenna and when that senses movement the lockout happens again within 30 seconds, not to mention the cutting the VSS wire makes the nav map track sporactically. (Basically, the GPS antenna is indicating movement, but there's no input from the VSS and the map has to update the current position.)

So the only common method to bypass the OEM Toyota nav is by installing a switch after cutting the VSS wire. You flip the switch activating (as if the VSS wire is cut), giving you about 30 seconds to put in inputs and when you're done switching it back (VSS wire is reconnected) so the map will track smoothly.

This works, but you have to willing to cut a wire..

This works great, costs about $25 for all the components, switches, relays, and such
