[CadillacSTS2003]

yup installed and is a truely awesome upgrade!
as for the nav command never tried to be honest
when i did my nav upgrade i had the 5 pin voice command however i never took it to the dealer to turn this feature on through the VCIM
i suppose when it goes in Monday morning i can askm while they have the tech 2 on her if they can turn it on and ill see if it works...
