I've had sort of mixed results doing that with the EC Offroad module (the one that works with the factory display) instead of CarPlay. The upside is that you get the full functionality apps, the downside is that the controls tend to be far less driving friendly (smaller buttons and generally requiring more concentration to use them). Having a larger screen rather than the factory screen would mitigate the downsides.
Using the hotspot on an iPhone can be an exercise in frustration as it will not automatically connect to something like these head units. Using an Android phone or a dedicated hotspot solves this and, at least with the EC Offroad interface I'm currently using, allows simultaneous use of Internet on the Android unit and CarPlay.
I contacted EC Offroad over the weekend with a few questions about my interface module (that works with the factory display), their current Tesla style unit, and asking if they anticipate newer Tesla style units (updated hardware, etc.) for the 200 series moving forward. As usual, they sort of kind of answered most of the questions

.
I asked about specifics on what the bottom left and right control knobs do on the current Tesla style unit: "The bottom left knob does AC fan speed, The right knob does in our case passenger AC but your case driver side master AC." This might be problematic when my dad or mom are passengers as they will inevitably be difficult to train to NOT touch the knob on the right

. It would be really cool if the knobs were configurable and came with several label options (or no labels) so you could use the left / right knobs for driver / passenger temp or use them for fan speed / driver temp, etc.
I asked if they had a video or a series of still photos showing the HVAC controls and they said they don't currently have one available to do that with.
Their reply regarding newer Tesla style units was: "We are working on a new 13.6 unit but still a few months away."
I've been looking around at Tesla style options that are compatible with my 2020 and it looks like, in general, the options are compatible with 2016 and newer LC's. What I've found is:
EC Offroad (obviously):

The ZWNAV looks like it's pretty much identical to the EC Offroad unit, but at a much lower price.
The aliexpress pricing of the ZWNAV may be deceptively good as it doesn't appear to include support for the factory 360 camera. The ZWNAV products on the Amazon link, at a higher price, specifically mention support for the factory 360 camera.
@kcjaz - looking at your other thread where you posted some photos showing the install, it looks like the EC Offroad Tesla head unit comes with a Canbus adapter box AND a separate parking assist decoder box - is that correct? If so, this may be where EC Offroad is providing value for the extra cost versus buying the ZWNAV products. Even though EC Offroad hasn't been good in my experience at answering questions fully or answering all questions when multiple questions are asked in a single email, answers can usually be obtained after a few back and forth emails and there's no language barrier to deal with.
I think I'll see if I can contact ZWNAV to get some clarification on camera support from the various sources, but it may just make sense to sit tight for a few months and see what EC Offroad's next version brings. I don't have a problem paying the extra money for EC Offroad if they offer extra functionality, but I don't really want to pay more than double for the exact same thing.
