The kit you bought will have the film for both infotainment screen and the gauge cluster. I bought the Tacoma kit for my 2025 4 Runner TRD Pro not only does it have the film for the infotainment screen and gauge cluster it also has film for the climate control and shift area's.
Beatsonic makes a plug and play amp. I installed it in my 2025 TRD Pro and it makes a big difference with the volume and quality of the stock sound system.

These are the one’s to get. I have had them in my 2025 TRD Pro for a few weeks and they are fantastic. Much better coverage than the factory mats and they are not slippery at all.
