thomashjr Report post Posted February 10 Hello: Just joined after just buying 2010 FFH with 72K on it. So far good except the BXT-67R in there now is over six years old and shows bad at autozone test in the parking lot. The car will "start" but overnight the voltage at the cigar lighter is 9.9V. Before I get autozone duralast replacement on their shelf, I need to know how to avoid a radio crash as I do not have any code numbers for the factory 6 CD changer AM FM Sirius with no navigation. Also, does main HVB need to be disconnected? Have no idea how to do that. Will stuff need recalibration afterward? Can I plug a 12V battery tender or backup device INTO the cigar port before any disconnect of the aux 12V? Would that eliminate these potential problems? Thank you.

On my 2014, I replaced the 12v just like I'd replace it in any car. Everything worked fine. Maybe I had to reprogram radio stations and pair my phone again but I can't remember for sure.

thomashjr Report post Posted February 12 Thank you for info on this; some of the folklore out there says the later cars do not have a radio code. I ended up going to dealer who charged me 199 for a 560 cca bigger battery and 40 to put it in. They told me they have a way of keeping power to the systems so the radio stays viable. They also stated it costs 189 to pull the radio out of the car and use a computer to read its code then provide it to me. For now just running merrily along trying to be optimistic about my future with this complex car. Quote Share this post Link to post Share on other sites
thomashjr Report post Posted February 12 It turns out the 560 will not physically fit in my 2010 so they put a new and same 390 in stating the system is designed for 390 not 560 so I guess I am happy about that. Just offering this in case anyone is contemplating stuffing a 560 in where a 390 belongs. Quote Share this post Link to post Share on other sites
