This is correct.  I just finished installing my remote start, "plug and play"  and this was the case on the 2011.  I purchased the kit on line for $180.00 which include 2 OE key fobs, (just had them cut) and a hood switch for $18.00.  Installation took about 1/2 hour. which included the time to reprogram the keys.   I then had the dealer activate the remote start feature on the vehicle computer.  They charged me $39.00 so my remote starter system cost $237.00. I had 3 dealers quote me $550 - 700. 
Works great!
