Support Thread for Speed Lock Override sold in the PC Shop

Thanks! I was looking for the side effects, and the service menu setting is entirely harmless, though I did not think of it.

Agree, any change at the head unit (grounding Park, 12v to reverse, VSS interception etc.) has to be localized to the head unit without any reverse propagation.

 

A quick question for those of you who've done audio mods like the nav override.

Do you disconnect the 12V battery prior to installing mods? If so, any issues in reconnecting it, or do you add a trickle charger before disconnecting the 12V battery so that the various ECUs still receive 12V?

 

In my previous car (Honda Accord), I changed the stereo, front speakers and headlights without bothering to disconnect the battery. Good to know that the same can be done in the Prius. However, I think installing an amp will require disconnecting it, especially if a new grounding strap is to be installed. I was curious to know if anyone had used a trickle charger/battery maintainer to maintain system memory in this case.

Thanks.

 

I just finished installing the bypass in my 2012 Plug-in-Prius base model, and SUCCESS (I think). The one difference from the install instructions is that in the post-installation test, mine never seems to stop bypassing when it's in bypass mode, the instructions say that it should stop after something greater than 2 minutes. Maybe it's a PIP difference.

For the installation instructions, the wire next to the purple wire that needed to be cut was yellow in my PIP, whereas in cpraudio's pictures it was orange. Made me double, triple, and quadruple check that my purple wire was the same as the purple wire in a regular 2012. If they changed the color of one wire, who knows what other wires they changed the color of. But the purple wire is still the right one.

Are there any illustrations or installation instructions for the Prius C? The V1 kit is supposed to work with it however I cannot find the instructions.

 

Thanks for the quick reply.

If I build up the guts to go at this without a tear down guide, I will do my best to snap photos as I go and sent that to you or post it. I just hate tearing a dash apart when the car has less than 1000 miles on it. We're getting ready to head out on a 2500 mile trip and I need to keep my wife's nerves in check. Disabled Navigation units might just send her over the top.

 

I may have missed it, but is there a schematic available for the v3v version?

 

I'd like to order a V1 for my 2007 Prius, but can/will you ship to Canada? Seems the PC Shop link will only allow US addresses.

 

2012 prius III took me 50 mins including test drive. Instructions were easy to follow. If you have wire cutters, rachet set with long extension, youtube on your tablet, electrical tape, pliers, light & you don't lose your bolts pretty simple job. No need to remove the glovebox or even unplug the whole headunit.

 

Will this work on PiP so that my passanger can check sports scores while driving?

 

The NAV software in my Prius has been upgraded, so no I Agree screen anymore. Plus to get the bluetooth menu, mp3 menu and address entry from Coastals Lockpick series, I have to buy the ultimate 3+ for $300... Not worth it in my opinion.

 

2012 PiP owners, FYI - this year's PiP harness wires are just like the 2012 Gen III hatchback described in CPROAudio's PDF instructions, i.e. the VSS wire is purple and lives in slot #17 of the 28-pin head unit plug. I just installed mine. BTW, it was easier to just unplug all the head unit (radio+CD) plugs and take the radio out altogether than to keep the thing balanced while I connected the wires, as the radio+CD box is fairly heavy.
