      2008 Upgrade to Premium Sound

      I've searched and read tons of threads but can't seem to find an accurate answer. I'm trying to upgrade my audio system in my 2008 XC90 V8 to Premium Sound. I have found and installed all the necessary hardware, door speakers, center dash speaker, and class d premium amp from a 2011 XC90. My radio and cd changer sound much better but I'd like to take it the rest of the way. I've read about a couple software downloads for the Dolby Surround that activates the center channel, but only for 2006 and earlier. Can this be done to 2007 and newer? And if so can anyone list the part # for the software? I know an Indy shop that has a real Vida account to do this instead of the dealership.

      2008 XC90 V8 Executive, Ember Black/Chestnut

      I thought it wAs the amplifier that stored the software for high performance and premium. The splash screen when you turn on the radio should indicate what system you’re running

    1. Is Premium Sound linked to the head unit or the VIN # of the car (2008 V70)?
