Has anyone added a CD Changer to their coupe? I have identified the correct Blaupunkt 5CD unit - a fairly inexpensive model approx 200 UKP ($300). Maserati want approx $1000 for this unit plus fitting would add a few hundred more - nearly $2000!. As far as I can determine there are some cables and some carpet trims required. Anyone got any info? Are there any software changes required for the information system?
