Navionics Chip for Garmin
 

I guess Garmin finally got the hint that their maps sucked and allowed a 3rd party to start making maps for their units. I managed to get chosen as a beta tester and my chip finally came in. I will let you guys know what they are like as soon as I get a change to use them.

If that chip does not work out for you, get the Garmin g2 vision chip it has aerial photo, satellite imagery along with a few other things I will never use.

Let me know how it works out I wold like one for my gar in 740s

I use the Navonics app on my phone because it shows the depth contours in much better detail. Hopefully this is just as good.

X2 on that, I use navonics as well on my android phone, great detail. Keeping an eye on this thread, as I am looking to either get the G2 SD card or something else.
