I have a navman 5500i tracker ,the zoom isnt coming up far enough to show water depths and hazards by pushing the + - button .is there an easy fix? Thankyou Muzza

Just got the same one and same problem, I also have a 5505i and is only zooms in close when i put in the c-map chip and it zooms close in the chip area only?? now i have a chip for the 5500i and it zoomed in but only on the Texas part of the map, that is the chip it came with, but i live in Canada. Be carefull the c-map max chip for the 5505i is not compatible with the 5500i it needs c-map nt+ chip. 5500 chip is black 5505 is orange

I have a Navman 5500 it will not read my C-map NT + card any tips on my problem thanks Stuart
