Hi the main reason people install in trhe glove is to keep the OBC the onboard computer intact and also the steering wheel controls. I have not installed that model
but read those threads you are referring to. I just clicked the liks.. it looks like another remix of the dynavin and hualigan from someone else. juust search the threads on here for dynavin and hualigan.. some say it has distinct bugs. Alot of post on it.
