No problem Brian, glad you can get some use out of it. Did you export waypoints/routes from your old unit? They're stored internally and not on the card. Power up the old unit with the card in it, once booted up, export the waypoints to the SD card. After that, boot up the new unit, let it power on all the way, insert the chip card and it will prompt you to import data from SD card. You say 'Yes' and all should be good.
