Removing "premium" (non-ml) Radio In 06 Non-nav Rx400h

[atebit]

Can someone tell me if there are any problems removing the "Premium" (not Mark Levinson) radio from an 06 non-NAV RX400h? I know that in newer cars, sometimes the radio is part of other systems that make it hard to remove or require a bypass. My plan is to remove the stock radio & replace it with an aftermarket radio, and I'd like to get an idea what other functionality I might lose if I do that.

Any help locating connector pin-outs or wiring diagrams would be appreciated!
