How much is radio and cluster 08 saab 9-5
 

Someone told me you had to marry a 114k 08 9-5 cluster to the 2006 160k mile car at the dealership? Simply swapping the radio over and instrument cluster wont plug n play? The stereo swapped has to be married at dealership or will a tech 2 work? Same with cluster.

I have a spare parts car 2008 9-5 aero. How much is a used radio worth these days and is there anything else valuable on the car? Whats a set of good 2006-2008 9-5 seats worth in good condition?

Are the miles stored in cluster or pcm and how much is 08 saab 9-5 auto transmission good condition 114k miles worth?
