How do these work?
I am wanting to paddle from Sydney to Darwin - but with one mSD card, how do I plan on my laptop/tablet at night, but read it in my Garmin handheld GPS from the cockpit by day?
And do I have the chart forever - or does access expire after a year?
It states that 'daily updates' can be accessed for 12 months.$350 for one micro-SD cardwww.whitworths.com.au/garmin-navionics-vision-microsd-north-east-inland-and-coastal-chart
