Sorry if i'm covering old ground if I am please point me in the right direction. I've been lookin through the menus on my bolero and theres one for bluetooth. Does this mean the head unit can accept a bluetooth module to make it intergrated ie disply call info on bolero screen. If so what do I need to do this please? What cost?

A few people have had success retrofitting the OEM bluetooth module (GSM III+). A quick search uncovered this thread where Ben from Shark Performance says that they install them for £350 inc VAT.

The bluetooth works best if you have a MFSW and Maxidot which Shark also install (not too sure on the current prices though).

thanks mate
