No, there is no problem with disconnecting the battery. There is no
anti-theft system on the MACH radio.
I have a 1999 Ford Explorer Limited with the MACH radio. I am about ready to
get a new battery and will install it myself. Do you know if the radio is
made inoperable by disconnecting the battery? My wife's Honda accord
requires a code to be entered if the battery is disconnected for any reason.
I would like to know if Ford has a similar anti theft ssystem.
