If you have not yet done so, please save yourself a great deal of time, and read THIS POST (http://forums.freshalloy.com/ubbthreads/showthreaded.php?Cat=&Board=M35M45&Number=68026710 &page=&view=&sb=5&o=&vc=1 ), before attempting to figure out how to DO the nav hack or the DVD hack. That's probably ALL anyone really needs to DO either.
Q2M ]

To watch movies on the navi screen IF you have the factory installed DVD audio or video system...

It will require that you install switches on 2 different wires on the harness that connects to the back of the navi DVD unit found in the glove box. (Silver box at the top of photo)

First you must remove the glove box so that you have access to the back of the navi DVD unit and the wiring harness.

Unplug the harness from the back of the unit (plug # M210 in schematic) and you will see that it is a 32 pin connector. You will need to find pins #64 (pink wire) and pin #66 (green wire.) All you need to do is cut both of these wires, tape off the ends away from the pin connector and add a switch to each wire that go from ground to the pin side of the wire. By adding the switchs you can then turn it on and off at will.

Be advised that both wires must be switched for the DVD to work while in motion. Also understand that once you turn off the spped sensor the navigation stops receiving info and will show you at the location where you first switched it off. Once you switch it back on it will recalculate your location.

It is that simple!

Have you figured out the hack for the Nav System itself, so that all features can be used while the car is in motion?

Thanks for the info!

Haven' tried to because it works fine using voice activation while moving.

Seems like there would be a real advantage to using the front screen for the rear camera while the rear passengers were watching the rearview mirroe blocking fold down LCD screen.

Can it be done while under way?

1. How do you remove the glove box?
2. What type of switch is used?
3. Does this involve the Nav DVD unit? The movie unit is in the armrest. Or is this just the way it is and does not involve the Nav DVD at all?

Awesome. So if you cut this wire and don't put in the switch and just tape the ends off will the front screen always be linked with the DVD and the rear or will all things work like normal and you will be able to flip from Cd to DVD, to Radio, to Nav, etc via the normal selection process?

I'm going to give this a shot, but I don't want to install the switch right now if all things will work perfectly fine without it and the only thing I'm loosing is having the screen not work with the DVD unless the brake is applied and the car isn't moving.

Ok Danny, I'm there and there are a multitude of connectors back there. There are 3 that go into a black box (I'm guessing this is one of the computers). This is 1/3 of the way from the Passenger door jam right before you get to the climate control blower where the filter is. Then there is two big white connectors labled Y03 and Y02 that are between the black box and the passenger door. these have a ton of wires running into them and as far as I can tell there are a multitude of pink wires being used on this car. I'm just a little leary of cutting any one of them. Here is a picture of the area I'm talking about and the connectors. I can't seem to find a 40 and a 32 by themselves. There are also two connectors below all of this at the very bottom, but they are very hard to see. Any help you can provide in identifying the right connector will be greatly appreciated.


This shows the area where the connectors are located

Thanks 50. I was thinking this was going to be pretty easy, but overall there are a lot of wires back there and there isn't much slack to work with. I'm guessing Danny went home for the evening, and possibly the weekend so I'm going to put the thing back together. Taking the glove box out wasn't all that difficult. if you open the door you'll see some phillips screws at the top of the opening. Take these out and gently push down on the glove box itself while pulling at the top where the screws were gently away from the dash. when you do this the whole glove box frame will pop out (there are snap connectors in addition to the screws). It will still be held on the right side as there is a cover over there that covers the side of the dash when the door is open. This is held on by snap connectors as well. You can pull that away more easily now. When you push down on the glove box the bottom cover (where the wheel well light is mounted) will drop away. Once the frame is disconnected you can pull the box out and it will slide off the frame (u connectors hold it at the bottom. There is a wire connector that connect the box to a device that lowers it slowly. You do need to disconnect that easily. Once that is done and you've disconnect the connectors on the glove box frame for the trunk bypass and the box light, the frame can be moved to the side. Then you can disconnect the connector for the well light and move that cover aside. You now have access to all the cables and connectors you see in the pictures.

We'll I'm going to put it all back together now. At least I konw how to get there when Danny replies as to which particular connector I should be playing with.

First you must remove the glove box. Behind it you will find 2 multi pin connectors. One is a 40 pin connector and the other is a 32 pin connector.

On the back side of the 32 pin connector you will find pin #64 (pink wire). All you need to do is cut this wire, tape off the end away from the pin connector and add a switch that goes from ground to pin side of the wire. By adding the switch you can then turn it on and off at will.

Danny...

I just followed your advice. I rear ended a school bus and it went off a cliff. can you provide me the contact information for your attorney? http://forums.freshalloy.com/images/graemlins/grin.gif

Seriously... A disclaimer on your post might not be a bad idea, I can see some yahoo following "your instructions" and, this being a overly litigious society, look for someone to blame.

It's a shame this country is so bad with that stuff. Danny you are fine with me, I'm only doing it for my passenger. In any case, that damn nav screen is there anyway and you think the driver doesn't look at that while driving???? In any case, I could find the damn pink wire anyway! It's all back together though. Not to hard to take apart if any of you want to try this. I'd rather not be the ginny pig with all those pink wires running off those connectors!

Or perhaps I do and don't know it. Lots of wires back there with lots of colors. Many with pink in them. Damn I don't want to cut the wrong one if you know what I mean! I don't think the warrantee will cover that!

Anyone know which is the motion sensor wire, in case someone wants only to make the NAV fully functional while moving? I'm assuming one is the motion and the other is specific to the video ...

This worked great...

I have to say I feel so much better about the car - not that the car was ever bad in my opinion - but with full control of the DVD and Navi.... this is incredible now!!!

One question...

The e-brake light is staying on. Is there a way to bypass this?

How are you guys dealing with it?

Thanks,

Glad to hear you're enjoying it. As far as the break light goes: Sounds like you've made a wiring mistake. The breaklight might well be ON when you're watching DVDs, however it should definitely be OFF when the switch is thrown to allow normal NAV operation (ie, the position that does NOT allow DVD on the NAV or full data entry in the NAV.)

Check out the wiring diagram in this post by EdH1. (http://forums.freshalloy.com/ubbthreads/showthreaded.php?Cat=&amp;Board=M35M45&amp;Number=67960924 &amp;page=1&amp;view=collapsed&amp;sb=5&amp;o=&amp;vc=1) If you have any additional questions about that diagram, please post it as a reply to that post, and we'll try and get you straightened out.

Q2M_from_LS430,

Do you know if the wiring is already in place for a ceiling mounted LCD monitor, as I do not have the Premium Pkg. If so, do you know what LCD Monitor is recommended fro the M.

The DVD hack is not available. The GPS hack will work, but it's not clear that the pin outs are identical (ie, that the wire to cut is in the same spot).

You should try searching the other M forum (the Q45/M45 forum) at fresh alloy for hack or mod. I know the approach works with the 2002+ Q45s (with diferent pin outs from the 2006 M, I think), and I'd guess it's 99% likely that the pin outs are the same for your M as for that Q45.

If you can't find anything for the Q or the old M the best bet is to get the service manuals on-line to find the Vehicle motion sensor pin (probably called VMS).

You can then follow the instructions for the single GPS solution in the other Nav Hack Thread (http://forums.freshalloy.com/ubbthreads/showflat.php?Cat=&amp;Board=M35M45&amp;Number=67952394&amp;pag e=1&amp;view=collapsed&amp;sb=5&amp;o=&amp;fpart=1&amp;Search=true#Pos t67952394) in this 2006 M forum (but using the correct wire as you will determine). That's basically how it's been done for the QX56, the FX, and the G35, just not sure you can trust that the VMS is identifiable by the instructions for each of these other models, without going to the service manual. BTW, when I searched for the Q's nav hack a year or two ago, I couldn't get the answer in the forum, but I was able to get it from the service manual. Unfortuantely I never did the hack, and I never saved the info http://forums.freshalloy.com/images/graemlins/frown.gif

There is also extra hardware in the Ms with rear seat DVD, so it is unlikely the wires are there.
