Speed Sensor Defeat Update

[butchbs1985]

Been busy at work so it took me a while to finish and post back.

After a brief yet colorful argument with a potentiometer, my board is fully functional and installed! One picture below is just the finished board and the other is the installed board. I mounted it to the glove box side of the wiring harness where the circuit is tied in to. All is working well.

For anyone else building this, I believe that Mike meant to refer to ping 6 rather than 5 for the 1.2V reference (at least on my IC).

Thanks Mike for the design work. I really despised not being able to use the keypad while driving!!

Glad you got it working Brian. Yup - should have said pin 6 instead of pin 5.

Ok, so this is new, but not really, since this is a 'dead horse' but based on the 'two-purple wire diagram I have seen, which one should I have to cut to watch video on a package #6 (no nav) Prius. Please advise, thanks!

When I want to dial a number while moving, I dial from my phone. It works!

Great. Thanks. Except I'm asking about watching video on long trips (for the passengers).

If your car doesn't have Nav then you shouldn't even see the NAV ECU wire. Have you looked?

seems we are in the same boat. i installed the sl2vi for my ipod touch and want to watch videos on my nav screen. i installed a parking brake defeat switch, now i need to figure out which purple wire to add a switch to.

also, from reading the 13 pages of this thread, it seems the main feature of cutting the nav purple wire is to be able to mess with nav addresses while moving. this thread also mentions that the nav purple wire bypass will time out, making you turn the switch on and off again to get 30 seconds more to enter your info.

i wonder if this will be the same issue with watching video on the nav screen? i am going to cut the wire in the next week when i have some time and find out.

on a positive note, i read someone on this forum has done it and it does work...

Haven't tried this mod but if the timeout does become an issue, you could simply build the timer circuit used in the NAV / BT override. That in theory would have the same fake out affect for video that it has on the NAV system.

Did this for a car with no NAV and it works like a champ! No timeout, I only had one purple wire and I cut it at the MFD, connected it a switch and voila! Only observerd drwaback are the disappearance of the '5 minute bars' and the rotating wheels. One side question, does the gloveboxe light stay lit, even if it's not open, when the headlights are on? Can someone please check this for me? If so, what's the glovebox switch that is supposed to turn it off? Thanks!

Stays lit whenever the headlights are on. It's an LED so very low energy use, more reliable and longer life than using a switch.
