Replying to: cluelesspa (May 01, 2008 5:22 pm) anyway this only enables the VIDEO in or DVD in from the entertainment to be viewed while moving. it will NOT enable entering data on the NAV system while moving. that seems to be tied to the speed. anything over 5 mph and its disabled. as far as this fix... all you do is pop off the trim plate (take a thin small flat screwdriver blade and work under the trim near the hazard light switch.) work that up... watch the wires connected to the hazard switch. the whole panel will come up. unplug the hazard switch (squeeze the little tab on plug and pull out). next unscrew the left and right little displays (unplug them and remove). they are held by the 4 gold screws (2 screws for each side). you will then have access to the 4 black screws holding the NAV screen in place. remove and the whole screen will come out of dash. pull half way then unslide the brown cable from the holder hook on top back of unit. pull unit out enough to unplug the 2 large bundle of plugs. one will be 16 wires (some not connected).. one will be smaller plug. anyway look for the ONLY solid grey wire (should be on the larger plug). Pin 13 of 16, I think... carefully strip back the black tape holding the bundle together and get back about 2 or 3 in from the end connector and CUT the wire completely. the part going to the connect (plugging into the NAV screen)... splice or connect a 4 inch wire of the same or larger size to the 3 inches left. then wrap the splice with electrical tape and retape the bundle. now reinstall the screen (feeding the new 4 in wire around the side of the unit. screw back in and attach the wire to one of the screws so the wire is in contact with the bracket (which is contact with the NAV case) which is Grounded ... there by grounding the grey wire (tricking the unit into thinking the e-brake is applied)... reassemble reverse order and presto Video screen will show video when pressing Entertainment/Audio Button on dash  while the SUV is moving note CUT and do not tap into the Grey wire. this way you wont see the E Brake light on your dash all the time. just tape up the un-used end of the Grey wire not connected to the plug side.

Don't know if this works on a Tribecca. Is the NAV unit under the driver's seat? If it is (as on my Legacy), all you need to do is ground one wire on the harness, and you will be able to enter directions on the NAV while moving. Very simple job.

Replying to: rs6er (May 06, 2008 5:43 am) I have only seen on other sites where they put a switch in-line with the speed sensor input and open the circuit when needing to enter data on the NAV. then flipping it back closed when done and the NAV will then readjust if done for a short period of time only. if not you have to pull over and let the NAV resync. But yes the DVD drive unit is under the drivers seat. not sure if that is also the NAV unit. |

Replying to: almat1 (May 06, 2008 4:25 pm) ====================== Originally Posted by #072 here are the pics and some more info. the wire that needs to be cut for the nav functions to unlock is green/black at the dvd drive under the driver's seat. on the road test this is how it worked. -when you break the conn. the frozen icons will light up -the arrow will stop moving on the screen -  10 sec. after you breck the conn. the sat. picks up your location and the arrow will start to move again, but its choppy - 20 sec. after you break the conn. the icons will freeze again, its figured out your still moving and locks you out. -breaking the conn. again will bring them back -it does'nt lock you out if your in the middle of entering a destination this seems to work okay, not flawless but better than nothing. leaving the ant. plugged in does seem to help it repostion you quicker after it loses you. |

never mind found it! sweet bla bla bla disclaimer, voids warrant, unsafe ... ok heres the scoop: ================== I've posted my theories up on other threads but here's an official write up on my tested/working way to unlock your NAV while in motion. I spent weeks studying the wiring diagrams on both Kenwood and Subaru (If people have access to more Kenwood diagrams I'm interested in seeing them). Turns out Subaru never wired up the parking sensor to the NAV unit under the seat. I have successfully grounded that pin on the wireharness and got the NAV menues to work while driving (see attached picture for proof). You need to ground the pin on the bottom row (2nd from left). Its the only pin on the bottom row that doesn't have a wire going to it from the Subaru harness. You can check your work by going to the NAV's main menu (main menu->Nav setup->Nav info->Vehicle Signal). If parking brake say's ON, then you have successfully grounded the correct pin. My picture shows some ghetto wiring because this was durring my testing trials. The white clip is just used to ground my temporary wire that I shoved into the harness. You will want to probably do a better/cleaner job then my pics show. Description of pics in order : -Label of the pin to ground to negative. (thanks to gnlowen, I borrowed his pic) -Closeup of the wire I shoved in the harness -Whole shot of the ghetto grounding job done for testing. -Proof of menu's not locked while car is in motion (I'd take a vid, but hard to do while driving by myself. You can see that the buttons on screen aren't greyed out) -Item to check to see if you have done it correctly ======================= from the Legacy group but supposedly works on the B9s.... not sure yet but will find out soon.. also the only downside seems to be that the NAV will no longer auto start a route. it usually if you drive long enough will automatically select the NAV route after you selected a destination. you have to hit START now after this hack. from what I read a guy did it on a b9. go from back of drivers seat. unscrew the two rear screws on the NAV DVD Unit cover and you can access the plug in question. its the bottom row of the wide plug see here:

Replying to: cluelesspa (May 06, 2008 6:27 pm) if you did this mod correctly you will see ON. if you do not have the wire in there far enough or the wire is too small it will not register (i.e. is not grounded). if you have Vers 2.0 NAV or Vers 3.0 you will find this signal in the HIDDEN menu. Hit MENU and hold your finger at the top center of the screen (where there is no buttons for 10 full seconds)... it will then pop up a screen asking for code. Enter 0412220 and hit OK then you can find the same NAV Signal screen. Leave the signal screen up if it says PKB = OFF. then try pushing the grounding wire in further until you it changes to ON. I used wire zip ties to hold the ground wire to the large bundle of wires above it (the antenna brown wire). that way it stays in.. reassemble the kick plate with the two bolts and voila you have NAV while moving capabilities!

just as an FYI ... that plug above where you grounded the wire. that is behind the brown antenna wire is the mini jack for the mic control button and the plug next to it is the input for the NAV Mic. You can use the Kenwood NAV Mic and it works. I have one on order (it runs $65 from Amazon shipped). just a plug and play option. read its best to have the NAV 2.0 or higher for it to work properly. you can then speak into the MIC to issue commands (like GO HOME). ect... pretty neat. cant wait to plug in the mic and command button.
