I just had the exhaust actuator replacement and Entunes update to 1.8.4 performed. The actuator replacement took about 3 hours. After the Entunes update to 1.8.4, none of my previously paired bluetooth devices would work, so I unpaired them and re-paired them again and they worked fine. The dealer initially tried to charge me about $50 for what he called diagnostics for the Entune update. I, of course, refused to pay and he removed the charge, but I wonder if anyone knows whether all of the updates for the first 3 years will be free.
They should be free. I thought there was an intention of being able to update over the air eventually.
