Hytech,
Your number 2 above is exactly how I read it in TSB Campaign 09-01-038-1
Page 6, Step 8-2 says; "HD Device ID" is shown as shown on the screen to the right (shows photo of screen). write down this ID number on yhour repair order, then select "OK". This ID number is required to get "Map Authentication Code" from the call-center or call-center website in step 9-1.
Page 7, Step 9-1 says; From the designated call-center; Make a call to the following number and ask to get the "Map Authentication Code". You will be asked for the "
VIN', "HW device ID" and dealer code if you are a dealer. (Then it gives the phone number)
(also, the "if you are a dealer" implies that those other than a dealer can do this, paying beaucoup bucks for the three discs - as for me, I'd just rather have a dealer do it, paying them to do the update and not worry about me making an error).
