Difference between Columbia 400 SL and SLX?

I’ve been trying to find the differences between these two models without success. Does anyone know what’s different between them?

Also, will Garmin’s SVT be available as an upgrade to this plane?

Thanks for your help.

Well, they are now made by Cessna, and if I am right, there is no S, SL, or SLX. The plane pretty much comes fully loaded.

Let me suggest you go to lancairpilots.org/ and register (non-member forum is free) and bring this question up to them.

If I am right, the SL was pretty much a bare model with Garmin (the s came with Avidyne). The SLX came with almost every option save a choice between air conditioning or Evade. I could be wrong, so don’t quote me on this.
