Did the radar, actually power up ?
You haven’t done a software upgrade recently have you? And do you have a fast heading sensor?
It may not apply to your particular model but earlier software would allow overlay without a heading sensor but obviously it was not synchronised and was therefore useless, the later software disables the facility unless it senses a heading sensor in the system. Also try the radar solo before switching to plotter and trying the overlay
Did the purple "sync" display in the top left corner ?
Have you set it for dual range ? as overlay is disabled in this mode.
Sorry mate, thought you were brighter than me, guess you just proved it
Must be in the set up tho
Hope you had a great time, Clive sent me a mail with a link to the photos, have you got it too ?
