Radio Security Code for HU-611
 

I have a 2000 S80 T6 equiped with the HU-611 Stereo. I still have the original battery in the vehicle, so I figure it's time to have some info in place before I actually need to replace the battery. Since, I bought the vehicle 2nd hand, there doesn't seem to be info in the manual regarding security codes for the stereo system. Is there a security code required for this unit? If so, I figure I'll have to go to the dealer to get the info. Also, how is the code entered? Any info would be appreciated.

Thank you,

Well, the dealer looked it up and apparently there's no code for this particular unit.
