Retrofit 2015 4runner with 2020+ Jbl headunit

I am looking to retrofit my 2015 limited trim jbl system with 2020+ jbl head unit for CarPlay. I found a jbl head unit from 2024, but not able to find any 2024 amplifier. Would any 2020+ jbl amplifiers work with 2024 head unit, or I need to buy a 2024 one?

Notes regarding JBL Vehicles:
If you have JBL in your vehicle, you will either need to install a JBL Entune 3.0 unit and swap the JBL amplifier from a newer vehicle or install a non-JBL Entune 3.0 unit (although this is not recommended and will require us to provide you with additional adapters). It is not possible to use the existing JBL amplifier with a newer JBL headunit. We have tried this and it didn't work for us. If you figure out how to get it to work, let us know! In the same vein, it is not recommended to install a JBL unit into a non-JBL vehicle. If you plan to do this, you will need the JBL amp to go with the unit and about $600 of wiring from us get the whole thing working.

The adapter for JBL vehicles is also different from the non-JBL adapter so please let us know that this is what you will be installing! In addition, we will need to provide you with additional wiring to adapter the connector for the new amplifier.
