The Locator works by taking an NMEA feed from a GPS and figuring out where it is in relation to its internal database. It then provides a single line of text with a plain(ish) language description of its location.
The problem is, that since upgrading the 530 to a 530W it's not been possible to get the two talking (it worked fine with the 530). I'm hoping that Garmin can provide a simple answer, and that it's just a setting somewhere in the unit's RS232 set up page - but if it's not possible I'll be looking for an alternative something or other to put on the yoke - I thought about an 'Aware' but I do a fair bit of Euro touring and I'd get a blank look alongside the blank screen about twenty miles into France. Any ideas?
