The Ghibli does not come standard with a bluetooth hands-free module. In order to get bluetooth, you have to pay $2890 extra for the base package. If you don't want to pay $2890 extra for the base package just to get bluetooth, are there any other much cheaper options to integrete bluetooth into the Ghibli? Could you simply buy an OEM Maserati bluetooth module and have it installed? If so, what is the price of that module and/or what website can you visit to look-up Ghibli parts. Any other options? Thanks
