My car has a USB and AUX socket in the glovebox but it seems that Maserati fit two types of USB socket - one that only recharges/powers an external device but does not allow data exchange, and one that is described as a full USB socket that allows data exchange and allows the media player to interface with the MP3 player. With this full socket you can download all the tracks on your Ipod/MP3 player to the jukebox or control the Ipod via the media centre screen. My car unfortunately has the recharge socket only (typical!) and I've no idea why Maserati have the two different types of socket. My dealer was also perplexed by this and is going to call someone in Maserati GB's technical dept for advice on whether the full socket can be retrofitted. I just wondered if anyone on here has encountered this problem and got a fix? I'm hoping it may be something as simple as fitting a new socket and reflashing the software on the media centre.
