Can the RX300 be upgraded with a larger screen, ventilated seats, and HUD? I like the 300, but I feel like these three features are hard to live without.

Currently, I've found out the costs for modifications: the central control screen is 12,000, seat ventilation is 4,000, and I haven't checked on the HUD yet. The central control screen vendor claims it's from the original factory, but I guess it's aftermarket and should only be worth 2,000-3,500. The seat ventilation at 4,000 is the price from the 4S shop, and it seems to be about the same outside.

In the domestic market, there's currently no option to replace the central control screen. It's not just a screen replacement issue; the entire front dashboard needs to be changed. The ventilation can be modified, but I'm not sure about the HUD.

Everything else is fine, but the small screen is really ugly.

Could you please provide more context or details about your question so that I can assist you better?
