I do like the CN digital display (which replaced my CN analog vario) and the thermal assistant it great. Yes, it does work with the same ADC used with the analog vario.

That being said you have to pay not both for the CN digital display (~$550) and an additional ~$600 (!) for the XC license. Ouch. Except for the thermal assistant I didn't really need, or want, any of the additional XC functionality* but, unless things have changed in the past year, the XC license is required to get the assistant.

Sure wish CN bundled this differently.
