Good Evening to All,

My car has the TV/SAT NAV screen but does not have the software for these features. I have had a look around for the appropriate discs and found several on Ebay for about £50 on average.

Just wondered which version is best/latest. I'm assuming a disc described as 'MERCEDES BENZ DVD AUDIO 50 APS 2007/2008 VERSION 3.0 SAT NAV DISC EUROPE' would be older than one described as 'MERCEDES BENZ DVD 2010 APS AUDIO 50 SAT NAV SATELLITE NAVIGATION DISC EUROPE'. But is there anything else I should be looking for aside for the highest number version and latest year?

Also, was thinking about replacing the HID burners, again found several and again just wanted to know which is best suited/correct for my car. The current burners work fine but dont seem to be especially bright. Would the ballasts need changing along with the burners or just the burners on their own?

Your assistance is much appreciated

Thanks
