Aha! Right, we all thought you had a pro head unit without nav. Yeah, a CCC is going to cost a fair bit more. You can upgrade to a CIC from an LCI car, but you WILL need coding for this. As with the pro HU, as long as you buy a CCC with the same options as you've already got then no coding is required. However finding one with DAB might be tricky. To be honest, the seller might not even know. Again, that said, coding in DAB that you've already got should just be a case of adding the DAB VO to the CAUDI module.
