bmurkoff Posted September 9, 2012 Report Share Posted September 9, 2012 I am trying to update the firmware on my x920bt so that i can install the new maps however being that i already upgraded to 2.003 it wont let me install the hacked version of 2.004. Does anyone know of a way i can downgrade to version 2.002 or if there is away around this? Quote Link to post Share on other sites
