I have a 2010 G55 that has a build date of April 27, 2010. From what I can find the first G55 models with mbrace were in the 2010 G-Class models built after November 2010. Would it be possible to add the feature to an earlier 2010 G55? Or won't it be worth it? I'm guessing it has to do with the "COMMAND" unit. However there are a few nice COMMAND upgrades with more features and up to Android 9.0. Has anyone here tried the upgrade or know if mbrace could be added to my vehicle?
