my vehicle - 2009 gs450h with nav and mark levinson sound

i love my new , to me, gs450h. most fun i've ever had driving. but i can't stand the lockout feature on the nav unit when the car is in motion. there are other people in the car that could navigate the nav unit - duh.

i've been reading and researching and it appears there is a relatively easy fix for my problem. i prefer a kit rather than splicing. it seems there are a few products on the market that will make me happy. before taking the plunge, i had a few questions...

question 1 - what unit do you recommend
question 2 - best place to buy
question 3 - any lessons learned or best practices you can share


thank you,

p.s. sorry for the lower case, my shift keys aren't working
