Disappointing but thank you for the clarification! I will look into aftermarket optionsNo. It won't and the factory nav is worthless. I have it and we almost never use it.
You also need wiring. It is NOT a plug and play.
Could you possibly ask your brother what model of Panasonic unit he had installed? I'm thinking about replacing my oem radio, looking for something similar. No NAV, no RES.That may depend on the trim and features. My brother had an aftermarket Panasonic installed on his '07 EX in place of his factory screen. Looks and works like the factory unit, and he now has backup camera and Car Play. He's happy with the replacement.
