does it give direction en route?
sorry, asked this of the 510 (wrongly) will this unit give directions en-route, and can it be loaded with a specific CIRCULAR route prior to setting off? if so, how is a route generated? on a pc then transferred? with exclusive software which is supplied, or at extra cost? on generic software which is available? if it does give directions, how? visually only? or paired with a phone and earphones too? much more detail on this unit is required. thanks in advance.
