  The Danger Zone

  • Do not interrupt power. If the ignition is turned off or the battery dies during the "Application Update" phase (minute 4 to minute 12), the RT3 becomes a brick. No dealer can fix it. You will need a $300 reflow service.
  • The "CAN42 New" mismatch: If you flash 663 Build 890 onto a radio built for a 2005 Dodge Magnum without the CAN42 gateway, you will get a "Bus Off" error. Check your vehicle's build date. CAN42 works for Model Years 2007.5 to 2009. For 2005-2007.0, you need "CAN25 Old."
