Is there any difference in quality and detail between the F units that come with Cajon Pass and the Pro Series F units??

Visually they're similar, but the new units are new models, using new maps, parts, and a few other goodies. Easiest way to tell would be to download the freeware v3 NYC AB set from the downloads section.

Cheers!

Thanks for the quick response. By the way, the RS-18 version 2 is truly superb!!

I'm glad you like it

Take Care,
