LOC not showing DME info

Question

Whenever I fly an ILS approach, I set the LOC frequency in the NAV1 radio.

The display (both Cessna and 737) show the LOC name correctly, but there is no DME information displayed.

What should I do it?

I've got exactly the same problem - not solved it yet.

I wrote to support and got back a Curt answer saying they use some database of data. That's it.
I have to say I was not impressed.
