Some benefits of early preventive maintenance:
· Increased speed of MCU performance
· Reduced risk of unexpected MCU failure
· Working internet browser (many have reported browser working much better, some sites remain unusable)
· Less MCU glitching (more stable)

Starting early 2020 our upgrade uses a 32 gig Swissbit chip running in 16 gig pslc mode to get much longer life, replacing the original 8 gig chip and extending life about 14 times! Other sizes are available on request.

I realize this post is getting long, but there is a lot of IMPORTANT information if you are doing the removal by yourself. If your missing a step you can find yourself with a DEAD 12V battery and unable to open your car doors. All of this can be avoided.

Signs of failure:
· Center display (MCU) is black and wont power on
· Center display black, but mcu still running
· Bluetooth connection drops
· 3G/LTE connection lost frequently where signal should be good
· Maps drawing slow
· Nav warning of no traffic data, when you can see your connected to internet
· MCU unresponsive
· MCU reboot randomly
· Stuttering streaming music (cached on eMMC)
· Stuttering AM/FM radio
· Age, the eMMC has a finite amounts of writes available (3000 cycles)
· MCU needs reboot daily to function without crashing
· Radio pausing every few seconds
· Voice command failing to work
· Browser not working
· Bluetooth and wifi not working together
· Trip counters not adding mileage

First thing to do, before anything else, if your seeing signs of failure, remove USB stick you may have for music or video storage. I've read reports of people not being able to boot up properly with USB stick in.
