cocosrandom Posted December 15, 2015 Report Share Posted December 15, 2015 I recently updated to the FX 3.1 but I'm having problems out of it like not being able to change my music or anything and I tried to do a fresh install but when I do it says sdmmc failed. I would like to just go back to the original f900bt software but I'm not sure how to go about doing so. Can I just download the latest firmware for my unit from pioneer and run it. I'm about to take a cross country drive and I'm trying to fix this asap Quote Link to post Share on other sites
