I recently bought a 2017 Outlander ES and I have the MMCS but I have the version without navigation. I'm trying to figure out how to reset the passcode as it already had one from whomever the previous owner was. I tried all the dealer codes I could find. I tried the holding the hang up for 2 seconds three times. I'm hoping someone can direct me to the hidden service menu but without the navigation button I haven't found how to do it. Any help is greatly appreciated.
