how do i get the anti theft radio code for my car?

If you don't have the code (check in the owners manual booklet) then you'll need to get it from the Volvo dealer near you: http://repairpal.com/volvo-repair-in-saint-petersburg-florida This will not have an effect on the convertible top, better have the shop look at that too.

Contact Volvo customer service US and with your VIN # they will give you the code.

I got the code for my radio last week with just the VIN number from the Volvo parts department.
