2019 -> 2022 radio issues, etc
I recently traded in a 2019 C300 for a 2022 C300, and have run into a handful of small "quality of life issues", which have changed from the old car to the new one. I'm curious if there's a fix, or "it is what it is"?
Radio Unit:
- If you use Sirius there are hundreds of channels to scroll through, so you need to create favorites. Except in the 2022 car, after saving 20 favorites it says the memory is full. I never ran into this issue with over 40+ favorites in the prior car.
- The scroll wheel on the 2019 C300 allowed you to the scroll through radio stations (and see what was playing) , while still listening to your current channel. It would only change the channel if you "settled" on a new channel and stopped scrolling the wheel. This was a great way to browse channels. With the removal of the scroll wheel, is this feature now gone?
- In the 2019 car, the volume change wheel used to change the volume in the smallest allowable increments. When I "swipe" the volume pad on the 2022 car, it causes a much larger and undesired change in volume. Is there any way to set or change the amount of volume change that is registered when swiping the volume pad?
