NW Iowa | I believe, unless you have the EST, deustch cable adapter, and usb to serial port adapter you can't install it. Most people don't have that. Also certain upgrades are not compatible with gen 1 and gen 2 FMX's. I like the 9.75 in the fmx and 11 in the nav. . Also most dealers will upgrade your nav for free, send it to them or stop by and have them do it. Every Nav I've done I've just sent to them. If you know how to do it different, I would love to know. | |
