Tiguan MK1 restyle climatronic types

[Filke]

Hello all,

I saw there are two types of climatronic in period 2010-2014, they look almost identical except one has "SYNC" and other "DUAL" button.

What is the catch are they the same or what?

Maybe I didn't explain well. I ment what is the difference between these climatronic air conditioners?
They both have all the same buttons except "SYNC" and other "DUAL" button?!
