Hi there - just a quick enquiry... The BM24 unit on my Alpina B10 is doing the cutting in and out thing so needs repair - no water damage as far as I'm aware - just the usual dry joint issue I'm hoping/guessing. I'll get it sent in in due course, but first of all just wondered if there were any possible upgrades/improvements that can be done do this unit also ala the BM54? I don't really need digital TV or anything like that, but is there any options for better power/sound quality etc on this unit? Thanks in advance - PM me a reply is it's easier? Cheers, David.
