Navigation System Override on 2006

No software solution has been found yet. There's a speed sensor wire that you can cut and put in a switch. Simply flip the switch to "Off" when entering information. There's another wire for the BT as well. Some have used magnetic switches and others have used a DPDT switch to operate both at the same time.

 

When this mod is done, does it only effect the MFD MPG calculation or does it also effect the odometer and trip odometers?

Maybe the better question is, what happens or doesn't work anymore if this mod is done without switches?

Has anyone asked their Toyota dealer if they can actually make a change to allow the GPS and Phone functionality during driving? That would probably be a liability issue for them, BUT, could they tell one of us?

Does anyone know a Toyota tech that may know for the right contribution to their beer or kids college fund??

 

To elaborate a bit more about the BT mod, turning off the speed sensor makes the car think it's stopped (probably the same with the NAV mod too). If you use the mod for a short while (like 30 seconds), you shouldn't notice anything.

If you're interested you can go to http://www.darelldd.com/ev/prius_speed_wire.htm to see some pictures of the wires in question. Also, take a look at http://priuschat.com/index.php?act=Attach&type=post&id=3457 to see how to pop the A/C vent cover off.

As I have a 2005, I didn't have to worry about the NAV wire, but I did do the BT override. I used a push-on push-off button. You can see pictures of that here and here.

 

Thx a lot gentlemen! I'm going to look at doing the mods tonight. Short of being able to make a software selection change, this is just the info I was looking for. Thx again!
