If none of the switches are working, they may not have re-connected the cables behind the multi control switch. It's easy to get to (compared the usual nightmare of working on our cars) but the dealer MUST confirm by inspection that the cables are connected. If they did connect the multi-switch and it still doesn't work, Follow Ilya's advise. Your dealer may not be worried if you're upset, but corporate might see it differently.
If they will not replace the unit, definitely buy one from Ebay as 04pathse suggested. I have an extra multi switch that I bought on Ebay to replace a broken button. I connected it just to see if it works like the original and it does. They can be had for under $100 - just be sure you get the multi-switch that has the NAV buttons.
