Found way around Navigation Unit

[Aurion ZR6]

Found this great web site:Nav speed pulse

I will make this Pulse Generator this weekend and test and see if it will work on the Aurion, which I think it will.

I will making the pulse generator circuit available here for $50.00 AU delivered to you doorstep.

This would allow you to Full NAV functionality all the time whether you are in motion or not.

Cheers Drew

Drew,

I just put a toggle switch in the speed Sensor wire going to the Nav Unit, ( I think I saw this on a forum some where ) and it seems to work fine, When the switch is Open circuit I can access areas that I could not when the switch circuit was closed.

The Toggle switch cost $2.00

Whats the advantage of the "Pulse Unit"

Is there any chance you can elaborate on how you did this, I would be interested in doing it myself.

Thanks in advance.

This little modification works for me I have a new Pressara, I put the switch into the Ashtray area, just to the Left of the ashtray.

2007 Camry Navigation Modification to enter destinations while moving, Adding a switch to defeat the speed sensor

There is a way to enter destinations while driving. I added a switch in the back of the center cubby. If you pull the radio/navigation unit out of the dash there is a gray plug that has 3 wires. The center wire is purple/violet colored and this is the speed sensor. When you are moving more that 5 mph the speed sensor ghosts out the input buttons on the screen keeping you from entering destination info to your nav unit. I cut this wire and connected a 2 wire speaker size line to the free ends of the violet wire and put 2 terminals on the other end and connected these to my secret switch in the back of the cubby. This works like magic. Going down the road I flip this switch and the ghosted out destination buttons on the screen light right up. If you are mechanically inclinded at all this is relatively easy to do. The only part I couldn't do myself was remove the air condition vent above the navi unit. Your dealer or a stereo installation place could do it for you. There are winged clips 2 on each side of the vent unit which must be pushed inward on both sides before the vent assembly comes out. After this you unscrew the shifter knob remove the 2 wings on either side of the cubby by pulling them straight out toward the back of the car. Then you remove the trim around the shifter pull it straight up and back. Then remove the top of the center console by lifting it straight up. Remove the 2 phillips screws holding the cubby in and remove it. The entire radio/navi unit and aircond controls are 1 unit and are held in by 2 10mm bolts on top and 2 on the bottom. The radio unit then pulls straight out of the dash. There are 8 or more connectors plugged into the back of the radio but you are looking for a gray plug in the middle of all these with 3 wires with the center wire being violet/purple, the speed sensor. I soldered my wires but you could use crimp connectors and a rocker switch #275-693 from radio shack. I used a dremel tool to cut a hole out in the back of the cubby between the power point socket and the ipod connector. I knew this could be done because I did a similiar deal to my 2006 prius. This procedure works perfectly on both cars and now I dont have to pull over on the interstate for my passenger to input things into the navigation. This may also allow you to input into your bluetooth phone but I haven't tried this yet, but I know there is only one speed sensor on the back of the navi unit. The prius has multiple speed sensors to the display so there are more wires to cut if you want to enable all the features once you are on the move. You will notice when you activate your secret switch the little wheels on the consumption screen will stop moving just like you are stopped. I know the early 2007 camry had a secret diagnostic screen you could access and people think version 5.1 of the nav DVD is the thing that enables this override button, but from my discussions with technicians the lockout is built int the nav unit itself and not controlled by the DVD disc, I have version 6.1 in my car. I had a toyota service tech look up the wiring diagram to tell me which wire was the speed sensor. I wish I knew how to post pictures but this description is pretty good. As long as you are gentle you won't break anything, but you will need to have a special tool or help getting the aircond vent out to do this. Hope this helps everyone. I just couldn't help it, I hated being locked out of my nav unit going down the road. This would also be a good time to add an XM receiver unit to your car as the radio must be brought out from the dash to plug in the XM harness into the back of the radio. The XM receiver mounts in the right side of the trunk above the battery, the antenna mounts under the back window next to the 3rd brake light. I got my unit from camelback toyota in arizona for 159.00 and the fit kit for 80.00. Be sure to get the 15 page installation instructions available only from a dealer and you can put this XM in yourself and save $200-300 labor. It takes some time 2-3 hours but since you are removing the radio anyway you might consider it.
