Had my C-max in the shop recently. A new 12V battery was installed. In the process I lost ability to SYNC my phone.As well as the Nav map feature. Not to worry,,,,though! The repair tech said, just go to the Parts Dept. Pick up the $149.00 memory (ROM) card and; update the software. My question is, that seems a little lavisciously priced? Any thoughts? Or, am I just being ;the Grinch?
