The GW 2012 units are an unknown quantity for me, but there is some info in [Only registered and activated users can see links. Click Here To Register...] in the thread 'Honda Goldwing 2006-2008 Navi GPS Firmware Update Version 4.60' together with a link to garmin. I also answered in that thread, [Only registered and activated users can see links. Click Here To Register...], a similar question posted by you but regarding 2006-2010 GW US models (which covers 2 other Navi models, both different to 2012). You probably should not really be asking for help specific to GW navi units in this thread bty. ;)
