I dunno for sure on your US cars, but the newer DVD disks include as software update that does allow destination entry on the move, this worked for me when I bought a 2010 disk, but I understand it came in from '07 onwards. BTW, if you use someone elses disk to update the Nav software and then put your own disk back, the destination entry on the move stays. Oh, one more thing about newer disks - you lose 3D graphics, dunno when that came in tho'.

It still gives you the warning about funcitons limited in motion, AND everything is greyed out while moving. One strange thing... when I upgraded the disc, the default search area / region changed. SO for a day or so I was like wtf is wrong with this thing. It would find a similar street name a few hundred miles away and insist that that was where I was going. I finally figured it out when I tried to enter the town first.
Take care,

My escalade nav also had the jaguar style lockout but the guys on the Cadillac forums found the simple fix of snipping the vss wire to the head unit which unlocked all the functions in motion. Supposedly this can effect accuracy if you are in an area with spotty gps reception I.e. a tunnel or something, but I haven't noticed anything adverse.
My range rover doesnt have any restrictions whatsoever enter the address as u wish.
Maybe something could be done with the jag??
Take care,

Simply start the car, leave it running, eject old disc from DVD, insert new disc, go back to drivers seat and view screen, DON'T SHUT OFF CAR until update is complete! Takes a couple of minutes. I just washed the car and watched for the home screen to return and that's it.

When you put the new disc in the screen should display "loading new software." If you DO interrupt the process it will still recover, but it takes longer and the screen will be completely blank while it does. That does raise the sphincter factor (ask me how I know!) but it will eventually complete the update and the screen will come back.
