Yes, that was the intent:

Tnnn for CTCSS tone
Dnnn for DCS code
Rxxm for miles
Rxxk for kilometers

We came up with RXXm instead of RXXM for miles since it it a
little more eye-friendly when glancing from the road to the
display.  The RXXM all kind of runs together whereas the RXXm
stands out slightly.  And so it seemed a little more
ergonomic...
