Does any one know the cost associated with a Sirus Install if the car has prep and also what the book say in term of labor hours and what the part cost might be... I am trying to work a deal with my dealer...

 

I paid something close to $625, which included about 1 hour in labor and the cost of the unit. A free year subscription was included as well.

 

I'll have to pull my workorder, but I recall it being $375 for the unit, maybe another $20 for screws and mounting hardware and 1.5 hour of labor. Grand total was $515 or something like that, before tax, so say $560 w/ tax.

 

Here's a thread that pretty much sums up what you're looking for:
