Have anyone tried to upgrade the LX classic head unit with the RX touch screen head unit? Is it compatible? Does car play works?

Sounds like a fun project, keep us updated!

It is 0% likely this would be a plug and play project. You can't even plug an EX head unit into an LX.

Why? Can you explain more please

All the different trim lines use different wiring harnesses

Probably, but there's a slight possibility EX and EX-L have the same wiring since they have the same head unit without navigation.

Well, you can start by buying short term access to techinfo.honda.com (and the Acura counterpart) and staring at the wiring diagram for the various cars. But I don't think it will help; an RX head unit is going to be expecting to talk to RX control modules, which won't exist.

And as far as the EX vs LX go... Both the climate control and audio systems are very different. Climate might still work, but the audio wiring won't match up. And the control modules might exist, but won't be coded correctly.
