Video/Nav Override

Found this site today for the front video override while in motion. Same for the Nav and XM scrolling .

Here is the link:
GM Lockpick

WOW! This is great! I bet a lot of folks will be thrilled to see this. The price is a bit steep, but people who really want this capability will happily fork out the money. I am really interested, but I may wait until the price comes down some.

THANKS FOR THE INFO!

I am going to order this fall. Hopefully the price will come down some by then. My wife and I travel alot to and from the beach (4 hr one way). This will come in handy when we leave for the beach on Fridays after work once the sun sets earlier...She can watch the movie and not watch the speedo....LOL

This is great! Can't wait to start dodging drivers watching TV. Thought it was bad enuf when I saw people reading a book at 75 mph or talking on a cell. Isn't technology great?

I have been looking for this since I bought my LTZ in April. Thanks!!!!

I was surfing ebay yesterday and found this very same thing on there...only they were trying to sell it for $450 and not the $250 that Coastaltech is selling for. I'll probably be purchasing this in the near future. I don't have the DVD system in my LT3 but I do have Navigation and this is supposed to unlock the Navi to play DVD's...someone please correct me if i'm wrong.
Thanks

it only unlocks the features locked out while in drive. you would still need a DVD version of the head unit to play movies.

Not being able to have a passenger enter an address in the NAV system is quite annoying. Has anyone purchased this unit? Does it really work?

I have this unit installed on my Tahoe as of today and it works as advertised.
To watch DVD you push the mute/voice command button on the steering wheel 4 times within 6 seconds.
To enter address into Nav on-the-fly you push the power window lock-out button on the driver door panel 4 times within 6 seconds and enter the address and then push it 4 more times to start navigating or this feature times out after about a minute.
Another feature that is included (but not advertised) is an orange 12V power wire that you can plug into one of the 12V outlets that you use to power your external accessory like an iPod,
this wire will kill power to the device when you turn the key off and open the door so you don't have to power the item down manually every time that you shut your car off.

The support from Coastal Electronic is decent.

ZX1100F1,
Does your Tahoe have the stock DVD system or is it just the regular front Navigation?
I have just the navigation system w/ out the DVD system in the rear and I was wondering if this GM Lockpick would allow me to play DVD's on my navi screen.
Thank you,
Jay

I also got mine installed today. The wood panel cover was a bit tough to get off, but I managed to do it without damaging the cover. The instructions also mention that it enables "bluetooth phone entry". I didn't think the Tahoe supported this? I know the nav/dvd system is made by Denos, but I haven't found much useful information online anywhere. I also don't have the navigation manual that should have come with the vehicle. My dealer owes me a manual.

Overall, a great unit.

do you have a DVD/Nav unit or a Nav unit?

Yes, I have the DVD/Nav system along with the read seat screen.

Jay,
The GM Lockpick will not allow you to play a DVD unless you have the DVD system to start with.

lk40,
Did you get a little treat in the box with your Lockpick?

Couldn't you just interrupt the signal from the speedo?

On the older model Tahoes that the folks are putting NAV into, on some models there is an orange wire from the speedo to the radio that
tells the radio that you are moving. Some used an interrupt switch to enter addresses on the fly.

lk40,

I did get the little treat. Still working my way through all twenty flavors.

To enter addresses on the fly that's basically what the GM Lockpick does is to interrupt the Vehicle Speed Signal (VSS), but it uses an existing button and it has a smart feature that enables the VSS every few seconds to prevent the system from triggering a fault code.
To play a DVD the system uses multiple inputs to tell if the vehicle is moving, even if you were to bypass the transmission position signal the DVD would only play for a second or two once the vehicle started to move without a device like the Lockpick installed.

Ordered mine last week and is supposed to be here tomorrow. Describe how you were able to get the panel off to get to the radio screws. Also, do you have to use the window lock button multiple times if on a long trip to scroll multiple times?

I used a very small L-shaped wire tool to insert between the dash and wood panel cover. I inserted the tool just above the center of the CD player opening. The simulated wood panel doesn't go all the way around the nav unit and at the top, it uses a very flexible rubber piece. This rubber piece is flexible enough to get a wire tool behind it so you can pull it out enough to get a flat head screwdriver behind it. After pulling on the rubber piece enough to get a firm grip on it, you can start to release the pressure clips used to hold this cover on. Just work your way around from top center and alternate your way down each side. The toughest clip was the last clip on the bottom center. I think it helped when I rocked it back and forth to work it loose.

This procedure worked for me, and I didn't have any scratches or any evidence that I disassempled anything (just fingerprints). As far as your other question about using the window lock button mulitple times for scrolling multiple times, I'm not sure. I haven't tested it that thorough yet.

Getting the radio trim panel off is a serious pain in the neck.
There are nine clips total, one at the bottom center and four along each side, the side clips are located close to the radio not the out edge and they are very stubborn.
I used a sturdy thin flat trim tool and carefully inserted it between the outer edge of the trim panel and the dash using a little force I wiggled it past its lip and behind the panel towards the radio until I could feel the clip and then pushed in on the handle to release the first clip and then just went around the panel popping each clip lose in the same manner, do not try to pull the panel off using your hands after the first clip is undone or you will break it.

To use the navigation data entry feature on-the-fly you push the power window lock-out button 4 times (I actually have to press it 5 on mine) and then you have about 1 minute to enter the address (it's plenty of time) before the entry feature reverts back the locked-out mode, the system won't actually start the guidance until the vehicle is moving (and it know it is) so you have to be in the normal lock out mode for the nav system to function anyway.

On another site that I found while researching this, they mentioned that while in the DVD overide mode, they were unable to adjust the volume. Is this still the case, or did they correct this?

Great info on removal of the trim panel. Mine arrived this morning and it looks like a night in the garage for me to install the lockpick and my new front "chrome bowtie"....

The bluetooth deal...exactly what does it do? What was the Tahoe not doing that this will enable you to do?

No problem with the volume while watching DVD's on the fly with my GM Lockpick.

Forget the Bluetooth reference, Denso also makes a Nav unit for the Toyota Prius that Coastal Electronic also offers a bunch of gadgets for, the Prius does have Bluetooth capability but not the Tahoe.

OK lk40 and ZX1100F1...So you've peaked my curiosity. What was the "special treat" that you guys got with your lockpick???

Might have to order one now so I too can get that treat!!!

ZX-

How does this get installed? Is it hard wired? I'm guessing it's not a modular plug??
