Mod: Speed cut to nav, to enable passenger to input address.

I think I've seen the Yahoo one too, and thought i'd bookmarked the link, but can't find it, the above one should help.

It's because it was Wayne who documented the Mod, but he quit the YG and deleted all of his posts and files.

 

Maybe, he did make a post about doing this to his '04, and he did, very briefly post pics of it and then deleted them. But, there was also an old post in the Prius-YG for doing it to the '01-'03s that I thought I'd book marked, but can't find now.

Anyway, the link I posted should help, but I'm not willing to go cutting wires unless and until I see detailed instructions and pics from someone else's moded '04. I sure wish Wayne would come back to the '04 Prius-YG or come here, or Prius Online.com or some place--his stuff was invaluable and it bothers me he left so abruptly and apparently in such a huff.

I think you have it correct, basicly. You're just disabling the 'dead reckoning' ability so for the time period that the speed sensor is disabled you could get a little off track. That's why everyone suggests a switch or timer be installed so that it is just temporarily disabled, long enough to let you dial the phone or program the NAV (in neither case you wouldn't be looking at the GPS map anyway!)

I just got my defeat switch installed. Here's what happens:
On MAP screen, in normal mode, the car icon moves along slowly. Flip the interupt switch and the car icon freezes in place for, by my "in my head" count, around 30 seconds. It then jumps to your current location and moves along in a more jerky manner updating the position every 1-2 seconds.

I assume that 30 second break is the system resetting...I think (no proof) that the GPS actually updates more frequently (like the every 1-2 sec. seen after reset).

FYI, I'll post pictures and details at a later time, I did things slightly differntly than Steven describes above....I chose to cut the wire where it's bundled under the center console and just add about 1 foot extensions to the cut ends to avoid all the threading and longer wires. I didn't unplug anything.

Also, see my other post, this mod does NOT allow full access, while in motion, to the bluetooth phone features....I suspect there's another wire that needs to be cut--shouldn't need a switch installed for that, just a cut wire I think.

 

You're partially correct. Some NAV features are accessible both via voice commands and/or the MFD touch screen. But some features must be manually typed in.

For instance...you're driving down the road talking to your friend Danny the Web Geek :mrgreen: and he invites you over for a visit. He gives you his address knowing you can just type it into the NAV and find your way. Well, you can't direct enter any address or even do a search for specific sites while the car is in motion without the MOD. Those buttons and screens are faded out and disabled.

By doing the mod you (ideally a passenger since it really would require you to take your eyes off the road for prolonged times) can directly enter those addresses or do a search for a site without stopping.

Hope that's clear.

 

Who are you referring to, there, Evan?
