Depends on your location...and what do you want the RR to do...are they doing mapping work & run(s) or just a power run to see what the car is currently doing?
If its just a run, then its more economical if you do it as part of a RR day...if not, then think it would depend on the map that they need, whether they have one ready to load, etc.
Could be a couple of hundred dependant on time, etc. But don't quote me, I'm not an expert!
