Hi

This has probably been covered dozens of times before, but I'm struggling to find anything that I understand. I have a 2007 GS TD4 with the basic sound system fitted from the factory. I don't want to fit a non standard head unit, but noticed that the manual said that the basic head unit won't play MP3 CDs. I like the look of a factory unit in a car, and have seen plenty of higher spec head units for sale relatively cheaply. My question is "what do I need to buy, and do to ensure that I can fit one and get it to work?". I have an ex dealership tough book with IDS so programming won't be a problem. I hope that one of you guys can point me in the right direction. Thanks for reading

Firstly I’m not completely familiar with the earlier model so may be wrong but I think the GS came with the non MOST ICE and the next ICE up is MOST so depending on how “handy” you are it will require a fair amount of electrical harness work inc laying a MOST ring plus some pretty involved CCF editing.

Thank you for replying. It all sounds a bit involved, but I will look at any options realistically.

Well it certainly more involved than taking out a head unit and replacing it, that process doesn’t apply to L359 MY15
