I have an autel ms906 that won't talk to my new used crossfire. Looking for recommendations on what to get that will. I spoke to a Mercedes dealer and he said good luck. if i try to manual get it he said to go in under the Mercedes slk171 not chrysler crossfire. I had better luck with the slk170. not sure what I should be trying or what scanner to get. currently waiting on needwings to rebuild my units.
