Hi everyone, I hope that someone can answer my question. I have a 2006 Ford Explorer Navigation Unit and when checking the configuration info I noticed it communicates with MS-CAN protocol. My question is, Can this unit ( 6L2T-18K931-BC ) be programed to communicate with SPC protocol instead of MS-CAN ? I would like to install it in my 2003 Lincoln Town Car. The unit works but no movement in NAV , only NSEW and the pointer is always flashing red even though it is receiving 7 sats while driving around. Any help would be appreciated. Thank you.
