While you've made some excellent points about the capabilities of the head unit and it's likely that the head units are basically the same, it's a bit charitable to suggest that Honda is willing to actually provide any of these features to previous MY owners. Specifically I would say this about wireless CarPlay, which they've intentionally excluded from the 2021 LX, base hybrid, and sport options, even though it seems like this is the same head unit we have in our 18-20 Sport/EX/L/Touring models. This seems like a way for them to add to the list of features separating the base trims from the upper models without actually doing much. And they can justify it by saying that the only models receiving it will have wireless charging and this makes it make sense....
So I think any 10th gen built before MY2021 with the Android head unit DOES have everything it needs to support wireless CarPlay. Couple that with the fact that, unlike older head units, this system is much more easily updated (thanks to Android OS), and assuming that the 2021 head unit is unchanged from a hardware standpoint, then we're looking at a semi-decent chance that Honda actually adds this feature in a future update.
I agree with you that from a business perspective, it may not be Honda's intention to update our head units with this feature. It's also a good example that they might be cherry-picking certain trims to have wireless CarPlay enabled. Still, I would not rule it out, especially because Tesla is setting a new precedent on vehicles software updates. Having sat in countless meetings with business people in product development, "keeping up with the Jones'" is not just for neighbors.While you've made some excellent points about the capabilities of the head unit and it's likely that the head units are basically the same, it's a bit charitable to suggest that Honda is willing to actually provide any of these features to previous MY owners.
Check out CPLAY2air wireless adapter for factory CarPlayI doubt it will happen, but I really hope getting wireless CarPlay is just a software update. If not, I’d like to find out what it would take to add the feature to my 2020 (replace the head unit with a 2021 version, etc.)
To date, OTA updates in Honda and Acura models capable of such are ONLY for the audio-navigation system - not for the powertrain, safety and driver assistance features, etc. like they are in some models such as those made by Tesla and some upcoming models by Ford, GM, and others.Over the air updates and Honda Sensing driver assist functions.
I believe I read that the new 2021 model year Accords had updated and improved Honda Sensing driver assistive technologies. Specifically adaptive cruise and lane keep assist. Its says it will maintain better lane centering and smoother braking when following another vehicle. My question is are these improvements some thing that Honda could push out to previous model years via the over the air updates? Or can they only update infortainment type improvements to the head unit?
