Lambos ARE Italian I don't know anything about a lambo kit for a Maserati but I know there are a very few good makers and lots of crap in that market. Hey, it's not my cuppa tea but it's your car... do what you like.
Do a search about the ipod kit. The Denison Ice Link is a choice but seems hard to find and the functionality is weak. There's lots of stuff here about it.
