There is MFD2 CD version (I believe black buttons)
I had this fitted to my car and good luck with firmware / maps
I did find a recent version of maps but no firmware at all.
There is also MFD2 DVD version (I believe silver buttons)
This is easier to find firmware and maps to download
I found loads but obviously not for my unit.
I upgraded unit to RNS510 latest version
Much better all round :D
