Nav/Dvd hack for 2010
 

I just got a 370z 2010 model with the nav. I wanted to remove the in motion restrictions on the dvd. I pulled out the nav/dvd and looked at the wiring but it doesnt seem to match the service manual.

Does anyone know which wires are e break and speed sense?

This is on a g37, but it is the same wiring setup as the 370

It looks as if there was a change between the 09 and 10 nav units. I looked at the g37 hack but it matches the 09 model service manual. The issue is that the 10 model doesn't match it. Here are some pictures i took. As you can see there is no pin 36/38 matching the color or location. The connectors arn't even the same.

I would recommend looking through the factory service manual to be certain before you start cutting.

Well that's the issue.. As far as i can see no one has the 2010 FSM just the 2009. The nav wiring is different for 2010 so unless anyone has it and can send it i will have to go wire by wire.

just FYI you need to cut TWO wires for the hack, speed sensor and E brake.

and when you cut the speed sensor, your NAV wont work while moving, its assuming your sitting there.

I almost did this but didnt have the switches at the time of which I had the nav apart. put it back together, got the switches and never bothered to go back into there. I really dont see why the wiring would be different on the 2010?

Yes i understand that it requires a switch to disable/enable the hack. If you look at the pictures i posted you can see the connectors arn't even the same size as the ones listed in the 09 FSM. There is a 32 pin connector and a 18 pin connector.

Where are the pictures you posted? The ones in the link from post #2 is for the G, so the connectors could be different. Also keep in mind that different versions of the Z within the same model year could have different connectors; but I doubt there will be a change between 2009 and 2010 model years.

These are the pictures.. The pinouts on these don't match the wiring diagram from the 09 FSM.

So i was right. The wiring on the 2010 370z is different to that of the 2009. I purchased the FSM on ebay. I uploaded the AV file to my site as you can see it looks like it's pin 65 for the brake and 82 for VSS.

hopefully this should help out anyone else who was looking for the bose navigation wiring as well.

mind doing a write up in DIY when you get this done? i wouldn't mind doing it as well

No problem i already have it apart so i'm planning on installing the switch as soon as i get home this afternoon. I will post a quick diagram and how to when i confirm its working.

Thanks for the pics, I re-upped them as IMG links. I can't tell by just looking at the connectors. Unless there are some MAJOR changes in the AV system, I'm almost certain that the 2009 FSM still applies for the 2010 M.Y.

Are you are sure you are looking at the right FSM diagram for the model WITH navigation and not the one WITHOUT navigation? I would check for you but I do not have my FSM here at work.

EDIT: Just saw your PDF post. Confirmed 82 for VSS and 65 for parking brake. So just ground 65 from the head unit and put a switch on 82.

Ok so i had some time on my lunch break. It worked perfectly. I took a few pictures and labeled the pins.

will this hack work in a '10 touring roadster with nav?

Yes i did the hack on my 2010 touring roadster with navigation. It takes about 40mins to do.

do you notice the nav scrolling more choppy than before or any other difference? i did this same mod to my Lexus and the nav got choppy because it could no longer compensate speed from the wheels

also, i'm assuming this mod will allow us to watch videos while on the move (not that i'd ever really want this feature but i'm sure my passenger might)

otherwise, thanks so much for doing the legwork...i've been waiting for someone brave enough to do this and report so the rest of us can enjoy driving without having to stop to change settings

The nav will be choppy if the switch is not re-enaged. The satellites are only polled perirodically. The rest of the time, the nav uses speed and direction data from the car to update the map.

Yeah i put in a switch on the VSS wire so that i can reenable it when im using the nav. Only other note is take the positive terminal off the battery before doing this hack to avoid the AIRBAG light coming on.

did you find a good place to put the switch?

Actually, warning lights will only come on if the car is powered up AND if one forgets to put one of the connectors back together. ;)

The best thing to do is COUNT the number of connectors you pulled and be sure the count matches when you are done. If not, go back and find the missing connector BEFORE powering up the car.

got another question for you guys - to get the menus to not gray out when driving over 5 miles per hour, all you would need to do is put a switch on the VSS wire and the purpose of grounding the brake wire is to get videos to play while moving? am i understanding this correctly?

THe VSS and ebrake are the 2 inputs the AV system looks at to see if the car is stopped before allowing video to play through the RCA connectors.

There is no software hack to do this? :(

No, the software itself has not been hacked as far as I know. The only way is to fake out the sensors into thinking the car is not moving.

if i dont mind the av system graying out things on the navi and all i want is to watch video from ipod for passenger then can i just ground ebrake wire and leave vss alone with no switches? thanks guys

correct me if i'm wrong but i am pretty sure it still won't work unless you cut the vss signal....it was that way with my Lexus IS; the ebrake was only part of the procedure. I had to put a switch between the VSS in order for the video to work (iPod/DVD).

Things have come a long way since this thread was last bumped.

People are installing carPCs and interfacing directly to the stock touch screen now.

and completed!....

all done and it works great with the seat heater switch mod.

Looking at doing this before the winter, can anyone that has done this tell me where they installed the switches? Maybe some pics?

Here's my switch. I used a momentary switch and it fits perfect and purchased here:

Looks awesome, only one switch though? Did you wire them both to the same switch, or did you only wire the e brake? From what I understand, only the e brake is required for video to work while moving and the other is so you can change the normally grayed out sat nav settings while moving.

I installed Navtool so I only have video input for DVD player and rear view cam while in motion.
