Ok Guys, I heard it was impossible, but with enough research i was able to figure it out. I have been looking for a way to unlock the Navigation while driving without have cut wires or do anything too major. Well here it is, It took me a few tries, but I now can drive and have my wife enter a destination or do anything else that is locked normally when in motion.
Ok In short here is the process that I used. It is hybrid of a few others i have read.
You will need a dual layer DVD +R (I used Memorex) and DVD burner that can burn Dual Layer disks.
1. Get v6.1 NavDVD's out and make sure they are clean. If not, wash them with warm soap and water and use a soft towel to DAB the extra water away.
2. Make a folder on your computer called "v6.1" and copy the contents of the v6.1 DVD to that folder.
4. Download and install ImgBurn,( The Official ImgBurn Website )set mode to "Build" Select source and point it to the backup directory of the NAV disc that is on your hard disk (refer to steps 1-3). Tell it YES that it is the root directory for the image content.,
Verify that file system under the options tab is ISO9660 + UDF, and recurse subdirs.
Add the UDF label to name the disc under the lables tab.
Press button to "build" ISO image. Give it a name.
Use NERO or other software to burn image on to DVD+R DL disk with book type of DVD-ROM. Book type for nero can be set under "Choose Recorder", Options, Book type settings.
Test disc in NAV system without pulling power yet. The NAV system will be able to read all the data on disc and give you POI's and new locations. The updated disc is now readable.
5. Next you pull fuse or neg battery cable for the 5 min. Then re-attach. Nav should pull new firmware and boot.
Turn on the car, and perform the following on your Naviagtion.
6. Press Menu
(menu screen appears)
Press Volume
(volume screen appears)
Press upper left corner
Press lower left corner
Press upper left corner
Press lower left corner
(Service Menu will appear)
Press and hold Over Ride for a few seconds
NOTE: If you are unable to get the SERVICE MENU up w/ the above procedure, this means you are still running v06.1 firmware ... please disconnect your NEGATIVE BATTERY TERMINAL & let the car sit for about 5 minutes ... then reconnect. This will clear out the NAVI's memory & when it comes back on, it will have to reload the firmware from your newly burned DVD, then the procedure should work!!
The above process worked for me. I got most of my information from the below link. Good Luck
From what I understand, the upper and lower left corner menu procedure must be done every time the ignition is turned on again, right?

Unfortunately yes, but it is easy enough to do. For one thing, I dont use the Navi every time i get into my car, so when I need to do it I will. I wouldn't be surprised if there another hack for that to. When I find it I'll post it.
Thank for reiterating this method. I supposed I will do this tonight.

To be quite honest, if i wasn't a software developer, I'd do it in a heartbeat for anyone, but since of the business i'm in, I can't just go burning pirated DVD's and shipping them around the country. Too much risk. But I assure you that you can go and get DVD burners really really cheap now a days (under $50) . The rest of the software is all free to do it.
What if we took a picture of ourselves holding the v6.1 nav disc in one hand, and a sign in the other that says "see, I really do own the v6.1 disc"? we could have our dash in the background...

Anything you do privately outside of TS is not under our control obviously, just go that route. Anything relating to copyright infringement can't be on TS at all for liability reasons.

Great news. If you are able to eliminate the menu override thing then you will get more fame than the guys who unlocked the iphone.....well maybe not but you will have thousands of ts members deeply indebted to you.....best of luck...
hey great find man! . but before i do all of this i do have a question, will this enable me to watch a dvd movie? thanks!
Not that I know of yet. I do know that lexus's and other Toyota Navi's allow you to. More must be possible, but I need to keep looking on how to do this now!!
