I missed my volume control knob on my old Honda Fit so much that I did a search on Internet. But I failed to find a bluetooth knob which I can glue to somewhere in my Clarity to change the volume. I know there is a volume control on the left side of my steering wheel, and another one on the screen of my right side. The muscle memory is just so strong that sometimes I want to touch the temperature knob to change the volume.
There are bluetooth volume knobs, however a USB one might be better. Assuming a USB one will work, since you'd have to power the bluetooth knob anyway, a wire won't make a huge difference. Bluetooth knob: https://www.sonicelectronix.com/item_95994_NVX-XUBT3-Universal-Bluetooth-Controller-Knob.html I cannot test this, since I don't have a Honda with the new Android based info system, like Accord, Clarity, etc... However, a standard USB keyboard and media controls work on most any Android device. I've plugged in my computer keyboard with volume controls into a few different Android devices (using USB OTG cable) and the keyboard and volume control works. So that means it's possible the Android system will accept keyboard and media controls by the USB port. But someone has to test it by plugging in a USB keyboard to see if it recognizes that. If it does then a USB media control would probably work. Not sure if the default setting of the Android system is set to allow USB input devices, there are probably hacks to turn it on though. So in theory something like this would work (seems a little large though), but probably there are other choices. https://www.amazon.com/LITROK-Controller-Computer-Multimedia-Adjuster/dp/B07GR864FV/ref=asc_df_B07GR864FV/?tag=hyprod-20&linkCode=df0&hvadid=241935719665&hvpos=1o3&hvnetw=g&hvrand=9178179765722941123&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9061200&hvtargid=pla-554405272004&psc=1 Here's another with extra USB ports, maybe smaller, but odd color matching. https://www.amazon.com/dp/B07QVKYZKP/ref=sspa_dk_detail_2?psc=1&pd_rd_i=B07QVKYZKP&pd_rd_w=cUqza&pf_rd_p=8a8f3917-7900-4ce8-ad90-adf0d53c0985&pd_rd_wg=6dXQA&pf_rd_r=KWXW872N0JEM9C8SQN71&pd_rd_r=5c1312d7-905e-11e9-bcad-3502a1b9f144
