Support Thread for Speed Lock Override sold in the PC Shop

I installed cproaudio's TSHRCA + SLO1 today on my Prius. I posted photos and steps for installation on a 2014 Prius on this thread:

Installation of Speed Lock Override and Turn Signal Hazard Rear Camera Activation on 2014 Prius | PriusChat

 

Love it! Did the same and it works great on my 2011 Prius. I haven't put the on/off switch in yet - I will use a DPDT toggle switch so it will power up the 555 board and simultaneously switch the VSS from the board to the Nav unit to enable the bypass. This should save a little bit of power draw when the switch is in the 'normal' (non-bypassed) position by removing power from the 555 board. I may also remove the LED on the board and mount it next to the switch to indicate the bypass is ON. The flash rate (~3.8Hz) is perfect for grabbing attention as a reminder to switch it OFF after use. If there is interest, I'll post an update when I finish it up. Total cost is less than $20; great find on the 555 module on eBay.

 

what about 2015 prius v (lowercase v for the Prius v wagon) ? which one do i order, also any recommended shops for installation? (careful for the interior not to scratch anything up) Los Angeles area

 

I would like to install the speed navi override in a 2012 Prius v in Canada. The Prius Shop doesn't seem to be able/willing to ship this to Canada. Has anybody on this side of the border done it?

Thank you!

 

Just installed the TSHRCA + SLO1 today in my 2011 Prius and it was a fairly straight forward process. The turn signal switching of the rear view camera works great! The only thing which is giving me problems is the speed override. When I activate the speed override the navigation buttons and audio buttons only stay active for ~30 seconds or so. They then return their innactive grayed-out state. Switching the speed override on and off again does not reactivate the menu buttons. I have to return to the display's home screen and turn off the override and then back on again for it to work, still for only ~30 seconds. The LED on the switch is active so I know I'm getting power. Is there any time of internal timer enabled in your system or have I done something wrong during install? Thanks for any help you might provide!

 

Just wanted to state, cproaudio was 100% correct regarding my issue noted above. All works perfectly now! Thank you again cproaudio for your help and making these great units available for purchase!

 

I installed the SLO1 Nav speed lock override in my wife's 2015 today and I cannot get the NAV unit into the service mode using the instructions on the link that I was supplied. I have tried about every combination of the instructions I was given and nothing seems to work. When test driving the vehicle the override seems to work as it should, but I would still like to look a the VSS screen. The only DISP button I can find is the one on the steering wheel, is this the correct one? I am hitting the power button without depressing the brake pedal to get it into Acc mode and then holding the DISP button down while turning the park lights on and off 4 times.

What am I doing wrong? Or did something change for 2015 from the earlier models?

Thanks!

 

OK, I figured it out. Again this is for a 2015 Three, not III because only 2010 used uppercase roman numerals for model designation, other years/ models may be different.

1, Put vehicle in acc. mode.
2, Allow radio/nav to boot up.
3, Hold "setup" button that is on the right hand side of the nav bezel.
4, Turn park lights on/off 3 times. Park is the second position from off.
5, Hit "next page" button on screen for the vehicle speed display.

I tried this numerous times and it seems to be the correct procedure.

 

So do I still need a SLO1kit in order to override the DVD Playback or is there a way to wire it without it? Read on it early by grounding the orange but I didn't see anyone confirming it. My main purpose is to play DVDs while driving.
My nav is 7in. JBL V1V I believe.
