anyways, I have seen threads that shows how this is dont on M/Q series of Infiniti but nowhere to be found for a 2005 QX56.

Anyone has a link for it or has done it and could point me in the right direction.

Btw, kptechnologies has a device but according to KP, device is not tested on a 2005 QX56.

Thanks!!

As for the ability to program while driving, you merely need to wire in a spdt relay (you can use your own or buy the kit with it included) to the speed signal wire.

I have this in my Titan. Works great. Though, my intent in buying it was to eliminate the legal disclaimer screen. The programming while driving was simply a bonus. Though I did order it with the relay and beeping device. I highly recommend the beeping option as I can barely hear the relay when it clicks over.
