Removing NAV Restriction

I am ONLY interested in removing the NAV LOCK while driving.

Is the lockpick my only solution?

My wife's old 2005 Infiniti FX35 had a DVD based nav system and the DVD unit was underneath the passenger seat. To disable the nav lock while moving, all you had to do was put a switch on the wire that fed speed data from the DVD unit to the head unit. It was the easiest automobile electronics mod that I've ever done. Somehow, I don't think it'll be so easy with a 730N.

I just picked up my 2012 with 430N - and I can pick from POIs while navigating. The only thing I cannot do is spell something out. Not a big deal to me as I usually only know the address of my destination. Any other stops would be for gas, food, etc.

Is that the way the 2011s are, or have they changed something?

We do this on the Fords and GMs quite a bit. It's a very simple Two pole switch $2.73 @ radio ShaQ. You interupt the VSS (Vehicle Speed Sensor) or (Velocity Speed Sensor) wire. I'm told from a friend over at Mitra the VSS wire on the 2011/12 GC media center units are Navigation wire colors:
Blue/Pink – VSS (Vehicle Speed Sense)
Green/Violet – Reverse​
Lt. Green – Parking Brake

Keep in mind they don't use the same language we use here, 430N, 470, RER, RHR, etc.. and Mitra online isn't listing the 2011/12 yet. So... I've asked him to confirm this 100% for me.

Now, I know there a few CHRYSLER/Jeep folks here, could one of you find a way to confirm the color code internally? If you do I will test it and report back.

The speed is digital data on the CAN buss, no way to disable/change it with simple switches. Something like the lock pick is the only option, but it does have side effects... like always showing speed = 0.

i was under the impression that nav will show 0MPH in any nav related speed 'quotes'. Is the nav system using vehicle speed data in this or internal satellite data?
Interesting. Being that the interface is Garmin (at least the 430N) and most all Garmins display speed readings (obviously from GPS) I am surprised the readout is not GPS based. I thought I would be able to check my speedometer versus the GPS readings, but I guess not.
