No timeline as yet. Customers will need to get on an email list with Furrion to be notified once a workaround has been engineered.
Were you ever able to make your camera system work? I ask because yesterday I had the nasty surprise of finding out my vision S system doesn't work with my brand new 2021 Sierra 1500. E-trailer is selling two different adapters from Furrion that are supposed to solve the problem. But...both have notes that say "won't work with 2021 vehicles". Their user reviews indicate good results with 2019 and 2020 Silverados and Sierras, and I would have guessed my 2021 would be the same?
The solutions that have me rewire the cameras or tinker with the truck wiring are non-starters for me. I love the idea of the plug in adapters and can't grasp why they would work on a 19 or 20 but not a 21?
