Welcome to Club Lexus, Twedwards3.
Am going to assume you installed this with the battery still attached to your vehicle. Believe the negative terminal needs to be disconnected on your RX before you hook up the connections to your new unit. You will need to disconnect everything, remove the negative terminal from your battery, reconnect the stereo, then connect the battery back up.
Shipment Mode is used for transport to park moving parts such as the CD player laser diode.
You might try confirming this with the seller on eBay.
