Mkgmap does parse them, but does not support them. There was some talk 
maybe a year ago that via ways might be possible to support in the 
Garmin format.

I made the parser modification a couple of years ago. It is not perfect.  
I think that you could legitimately have a sequence of multiple via ways 
in the relation (in case the via way needs to be split because of a bus 
route relation or such). The current parser would complain if there are 
more than one via way.
