Hi Serpentor, thanks for the information. But I got a question. How did you know you found a 2017.5 head unit? Did you do a search on the VIN number? Or was there another way to tell the radio is from a 2017.5? Thank in advance!
Is yours a stock radio or Bose setup?
Did either your radio or the replacement radio have navigation? EDIT Sorry I forgot that you mentioned that you wanted updated maps, me bad
Answers will help others make the decision.
Thanks and have a great day.
