I went through all of the "D" series posts and couldnt find an answer and method. Can one DL nav disk be made from both disk so im not swapping disk? If so, can someone point me in the right direction? Thanks

No. It's too much information for one double layer disk to hold.

Is there a way to make a custom nav disc for the D2 with just the states you want as long as you stay within the capacity of a DL disc? I travel a lot all along the southern US (coast-to-coast) and very rarely hit the north-east US.

Any thoughts???

Nope
