speedometer

All I want is to have this updated. It should’ve been done when the whipple was installed at the dealer but it wasn’t. Would take it back but it’s 3 hours away. What can I use to do this myself? Not sure if this can be done with Forscan on this gen.

ok my 2024 eco prem was acting up rear view camera wouldn't come up at times display would go black for periods of time local dealer ran a test process and said the unit was defective ordered a new one 10 days later stalled up and running no issues until 2 months later last week...
