BMW Radio- options

[Marc]

I am on the search for a 2011-2012 Polar Silver RT with ESA and a Radio.

 

These are items I am having a difficult time finding. I found bikes with ESA but no radio.

Does anyone know if the radio can be installed afterward? Cost?

I am tired of the autocommand would prefer the sound system.

 

Any recommendations would be appreciated.

 

Thanks.
