Upgrade Navigation DVD

This may be a dumb question but I tried Google and didn't get an answer...

I can just buy the newest Nav DVD disc anand swap it with the stock 2011 disc.. I don't have to do any weird data save transfer stuff right..


Also anyone know where you can get the best deal on Nav DVDs .. wife drives a 2011 Sienna. (RADIO E7027)

 

Sorry.. it's a Sienna. . Wife van

 

Throw in the man card

 

Bro, I drive a Lifted Double Cab.. but if my wife wanted to trade in her FJ for a Van that is her call.. 3 (1,4,5 yo) kids wont fit in the back of an FJ

 

A cheapest price I found was TRD parts 4 U http://trdparts4u.toyotaofdallas.com/Scripts/default.asp

If you have DVD, yeah the only thing you have to do is eject Old one and put new one in. It will keep your points and data saved to memory.
