It's been talked about in the main thread about the headunit swap and no it's only for the old style headunit that you can change the start up pictures.

the 2022 HU arrived, minor blemishes as expected but overall good condition. Orders placed for the necessary wiring to complete the install. Will hopefully be completed by next week sometime.

I had originally installed the OEM Audio+ full kit with amp and sub into my 2016 4Runner Trail Edition Premium (TEP) with my stock head unit, non-JBL. The sound and volume level was much improved over stock.

I then installed the $600 Car Trim Home (CTH) T10 V2 head unit with Android Auto, wireless Carplay, navigation and 128 GB of storage. I absolutely loved this unit for its fast and large 9" screen, apps like Gaia and custom vehicle telemetry data and graphs with OBDLink MX+ OBD2 Bluetooth scanner with OBDLink app but the sound quality of this unit was muddled and tinny, even after playing with the EQ and getting to the best possible position. The problem was the audio hardware on the unit. It was so poor, I couldn't listen to any audio at all but I still loved the unit for all the other features. However, the unit died and black-screened after just 3 months of use. I just can't deal with cheap stuff that doesn't work well.

Wanting great audio more than built in Gaia and OBD2 data, I purchased an OEM Entune 3.0 4Runner head unit from a 2022 T4R with the retrofit adapter kit from Entune 3.0 Install kit for Toyota vehicles - Add Carplay for $2450. It's installed and works very well. Still, I wish it had the ability to install Gaia trail maps and use the OBDLink MX+ OBD2 Bluetooth scanner with OBDLink app. Back to duplication with the iPad and xGPS unit to get trail maps. I guess we can't have it all.

What are you all doing for trail maps as far as apps and hardware?

Gaia works with CarPlay so you can still use it. Mostly though I have an 11” iPad on a mount that’s used for mapping off road, again with Gaia. If you go the ipad route, make sure you get one of the cellular models as they’re the only ones that have a gps chip built in.

Oh interesting. Can you use the cellular model iPad without the cell plan and use the GPS for free or do you need to buy a plan?

Don't need to buy a cell plan, but the only way to get a GPS chip in the iPad is to buy a cellular-capable model
