 Your advice is needed
Just taken delivery of my Mini One and love it. The only down side is I HATE the sound system. I had a 6 CD Autochanger installed but didn't upgrade to BOOST. I've gone back to the dealer and they've quoted me £377 to upgrade it - a bit steep for my liking! My questin is what are the alternatives and would they invalidate any of the warantees and would any other radio fill the space on the dash ? |
