My Acura MDX was stolen and recovered last week. It was used we
think to commit some other crimes. The Nav system records
previous vehicle location and indicates dots on the screen if the scale
is small enough. Does anyone know how or if this data is able to
be output. If we could get a time and date for these dots we will
be able to make an arrest in this case. Your help is appreciated.

I would leave it for the cops to investigate.. why get yourself between this and risk your life for some one else's issue... it could be gang-related for all you know? Hmm.. I'd just get rid of my car too so I didnt feel like a target while driving!
