I’ve used the Grom Bluetooth adapter in my 2006 LX for years and it works well. No Apple Car Play, but the Bluetooth works and gives me 90% of what I want. Bluetooth adapter car kit interface Lexus LX 470 2007 - https://gromaudio.com/store/bt3_adapters/all/lexus-lx-470-2007-bluetooth-adapter-car-kit-interface.htmlMy big debate now is a nice single din that will integrate and look "natural" or a double din car play head unit. All I really care about is being able to stream music via Bluetooth and USB. Car play is nice, but in my experience relatively glitchy and not a must have for me. I wasn't super impressed with it in the '21 Tacoma and the '20 F-150 I'd driven for work the past few years. A backup camera would be nice though.
On a side note, did you buy an adapter harness or direct wire it from the head unit?
