I recently bought a VF2 Calais with heated seats, after searching around, most don't have cutouts for the heated seat switches, however there is 1 listing that I found that does have the cutouts for the switches.

Unfortunately it looks like this is the only option to get a head unit suited for the heated seats. Although without having one here or the instructions I'm unable to even see where you would plug the switches into or if they would even work?
I was looking at the one VF300K posted but would require some modification to make the switches work.
If it's anything like this post:

It's not "plug and play" and way above my pay grade.
Im a bit tied at the moment between a ksmart module and a complete unit, I would love to keep mylink as the factory buttons are useful but after today's trip (misses has been driving it since I bought it) I'm fairly disappointed in the stuttering on bluetooth the whole hour I was in the car and I have a feeling that a ksmart module will do the same. And not keen on spending $500AUD for a ksmart module for it to stutter and also not keen on spending $550 for Unit to arrive from China to find out the heated seats won't work with it or doesn't have cutouts, when I can buy a $270 Unit that I know definitively doesn't have heated seats.
