Hello, this is my 1st post since becoming a member.
My question is: I borrowed a Navionics premium chip from a friend and could not get the map of the lake I was on show up with any detail on my 858c. Each time I zoomed in it would show as "over-zoomed". The chip is a couple of years old and did see on the Navionics site that the lake I was on is listed as a high-def map. Any ideas on what the problem could be??
Also, Is there a way to look at the maps that are on the chip while at home and not at the lake?
I would like to thank all the members on the site for always being helpful and super informative!!
