Speaking of the DSP system. Bought my E39 a year old and the origional owner didn't elect to install a DSP system just the normal radio. Is it worth investigating an upgrade to a DSP unit? If so how does one go about upgrading?

Save yourself the trouble and just forget about "upgrading" to DSP. I'd start looking into aftermarket audio. Diamond audio is supposed to be pretty good, and MB Quart has an excellent component system for the M5, if you have at least 4 grand to dump into it. I'm in the process of upgrading my DSP and I'm pulling my hair out. Maybe I can be of help since I'm only about an hour from you.
