: Enable DVD when driving. Is the disabling based on software?

In cars the DVD Video on the front screen isn't allowed to play when the car is in motion. The bypass in most cars is to just ground the parking wire to the unit. In this case I assume there isn't a parking wire and it is all software based? Anyone have any idea? WOT (I know you don't recommend doing this, but it would be nice to know lol). Anyone even begun to look at a hack for this? I don't need it for myself but it would be nice for the kids....

Thanks,
P

PIt's all network and software driven. All GMs with front mounted DVD systems work this way.I've not heard of a hack, but won't dispute that it's "possible".
Sorry

Well if it is software driven on all GM car's then that is great news. I added a hacked box to my 2007 tahoe to allow navigation input and DVD playback while in motion. I was always under the assumption it was grounding parking break wire to allow playback. If it is software based and they have done it on other models then the hack should be out at some point. Good news. Thanks again

Something I received today from a company called Solid Signal. I don't know if the device will work with the Volt, but who knows.

I bought a similar device for the Prius from Coastal E Tech, it worked great.

This reminds me of a hack that I did on an IBM mainframe that I worked on about 35 years ago. I was studying the microcode listings that had been thrown in the waste can. I wanted to play with modifications to it. I discovered that there was a memory alter/display utility as part of the microcode. The problem is that it was disabled by a hardware lock that required a key that the "CE" carried. Then I discovered the test for the CE key - it was a single bit to be tested and only required a single bit to be modified. Then I found a single hole that had to be punched in the microcode deck (yes it was a deck of punch cards). That caused a checksum, but that was fixed by a single additional bit in the checksum. After that I could alter the microcode to my heart's content. And oddly, by altering that one bit it now REQUIRED the CE key be off rather than on. Almost got undone once when I left my altered microcode in the machine and a CE made an unannounced visit. He put the CE key in and just could not figure out why he could not display memory. It seemed to clear up when he reloaded the microcode (with the standard deck).

I actually own and use the lockpick for my 2007 tahoe. It is awesome. I got mine in 2009 so it may be slightly different WOT can you look at the harness in the link above and let us know if the volt has something similar or is it completely different and new for the volt? If it's similar I can try and install it in the volt barring someone tells me how to get to the harness lol. I assume it's completely different due to the console integration into the navigation. Only thing that sucks is I know someone can make something that works but with the low amount if production cars being made over the next couple years it may be 2-3 years before it's worth someones time to make and sell to make some money.

Btw, Is there a volt service manual out yet?

I presume that the service manual will be available to purchase. I see that it is a Helm manual as most other US cars have. Now I wonder; how much?

It is supposed to be available April 15, 2011, and I think the price was going to be $150.

I'm more interested in being able to input addresses into the Nav while in motion (i.e. if I have a passenger, they should be able to do it while I'm driving). Does anyone have a wiring diagram showing how to get to the nav harness and pull the speed wire? I am assuming this would allow address input while in motion.

One of the things I hate about all factory NAV systems is you can't input info while moving, I almost did not get a NAV unit till I realized you can just push a Onstar button and they will find and down load your destination to the NAV in about a minute.

Also wouldn't it make more sense to buy a 9 inch portable Sony DVD player for $127 LINK (http://www.amazon.com/Sony-DVP-FX970-9-Inch-Portable-Player/dp/B004U5QE4M/ref=sr_1_1?ie=UTF8&qid=1325558220&sr=8-1)

Or I consider a Blu Ray player a better option, you can get a nice 9 inch B/R from $250 to $500 it we free up the console screen to display weather, climate, power flow and NAV screen.
LINK (http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Delectronics&field-keywords=blu+ray+portable+player&x=0&y=0)

It makes more Sense to me because lot of movies I rent from Block Buster are Blu Ray

You have 3 free years of Onstar, all you need to do is push the blue button and On start will input the address for you, try it nex time you are in the ca.

Reviving an old thread, but has anyone tried NavTV (www.navtv.com).com 's solution for video in motion? The install manual for their Volt solution is here. It basically interrupts the GPS signal and allows DVD in Motion, as well as Nav input (although you have to turn it back off for Nav to track and work).

The link to the installation guide is HERE (http://navtv.com/userfiles/editor/file/manuals/Barracuda/Volt%20VIM.pdf). It seems to be all plug and play, was just curious if anyone had experience. It looks like it would also allow additional video inputs for those models that don't have DVD capability.
