Have an 03' ls without factory xm and want to add sirius, have found unit for 03 up gm and hear some say it works and some it doesn't, looking at the dei sirius unit and trying to get it installed this weekend... anyone know for sure if it'll work or have this in your monte??? i have the am/fm/cd player with station and info display, the unit also has the band and cd/aux buttons as well... any help would be appreciated asap as trying to get it all together for saturday!
thanks

 

yes, the GM Bus II application from sirius will install very easily. I have heard that a professional install will take less than 3 hours also....
