Axiom 9 Navionics

Hi Chuck,
I have an Axiom 9 with Navionics Platinum Plus chart. The area covered is Lake Erie, Lake St. Clair and the lower half of Lake Huron.
Chip # 649P+
I can't get the auto route to work. Is this an Axiom software or Navionics software or operator problem.
I have a 4 year old IPad that auto routes very nicely.

Thanks in advance.
