Can someone please help - just got two new HDS Gen 3 - screen pop ups to download software updates.
Do I need to insert a SD card to download then take the SD card out or leave it in ?
When I load my new Navionics plus chip do I leave it in the unit or take it out ? And do I then insert SD card to download the Lowrance software updates ?
Tried to call Lowrance twice but keep getting message their office is closed —-also checked utube but cant find this specific questions.
What capacity SD card do I need ?
Thanks for any help !
