I just seen a evo max 4n for parts only on sale on ebay you may want to check that. As far as the parts though I'm not sure if there is anyone who sells just parts. Autel hasn't authorized anyone to be a parts dealer. Nor have I seen anyone else selling parts for it. Normally you would have to go through autel themselves to get what you need and they'll end up telling you it can't be fix3d that you'll need to just buy a new one
