I don't really understand that sorry, if I am riding in a group, wind noise and pipes even with ear plugs I couldnt hear a sat nav. 80 or 90 mph sweepers its quite loud, but something that indicated that in 3 bends time we were getting a 30mph hairpin would be handy.
I will make do with a map til then, (or follow Robbo )
