FINALLY!!! Waited 4 years for the FSD promise and my MX just got the long-awaited computer and super snappy MCU, like snap you neck kinda quick. Plano SC service center was great for the most part, except all the service advisors and Fremont customer service reps who are all completely oblivious to what exactly is happens with the MCU upgrade. It's been an emotional rollercoaster since May 8th when I got approved for the infotainment and FSD computer upgrade. Everyone I got to talk to kept assuring me that I'm only getting the infotainment upgrade and within that only the MCU (main touchscreen will get replaced/upgraded), even when I dropped off my MX this morning, the check-in advisor confidently confirmed, that it's just the infotainment upgrade, just the main screen nothing else. I kept asking, "But the service invoice has 2 line items and two separate components, along with 4 new hex nuts". The advisor insisted I'm mistaken, the SC has done a number of these now and only the AP2.5 Tesla are currently getting FSD computers. Well I sighed and said Oh well, I'll have to come in some other day. I was really thinking about getting the newer graphite trim pieces added but them opted out last minute. What I did add to the service request was to replace the cabin air filter, which is a $24 part and $19 labor, total extra cost added $45 dollars (shouldn't have charged me labor since they were already inside my dash replacing the FSD computer. But this was much more functional to me than the trim pieces. 6 hrs later, I got a call from Ray, super great manager, saying "Great news! We have completed all your assigned service tasks including the cabin air filter. As an added bonus, we were able to upgrade you to FSD computer, and we also got you a new IC unit. So you got 2 new units in total. They all come together in this big kit with your VIN number and labeled as Infotainment upgrade". So lesson here is as stated above, if you have FSD pre-paid and you want the infotainment upgrade, Just ask for the infotainment upgrade only, nothing else, otherwise you'll get really confusing answers and replies. Prime example where the right hands don't know anything about the left hand. I hope this helps. P.S. If you're on the fence about the infotainment upgrade, GET IT!!! It's totally worth it.
Lastly, all settings were transferred, except the WiFi. Pulling into my garage, my MX will not connect to my 2.4Ghz or 5Ghz SSIDs. I get IP address and DHCP error. MX connected just fine prior to the infotainment upgrade. I had to setup a new guest network for my MX to connect to Wifi and download new maps post upgrade. Anyone else had this issue.
