HDS 8 gen 2 insight Can I get a good mapping upgrade ?

[Bobby05]

I bought a boat and it came with a hds 8 gen 2 insight. Is there any way to upgrade the maps that came on it ? I didn’t know if there was a chip or something I can buy that would show creek channels and contours of the lakes like navionics or something similar? If there is how do you upgrade it. I found all kinds of info on newer lowrance but the older gen 2 I can’t find much info on. Thanks in advance.

On my buddies HDS 8 gen 2, I put my C-Map Reveal SD card in one of the card slots and it shows contours and will allow contour shading. C-Map does not work on HDS 8 Gen 1.

According to the CMap website HDS Gen 2 touch will not show HRB so that would be all your 1 ft contours, Does it show 1 ft contours on your buddies HDS 8 gen 2?

You have two full size SD card slots each with a max 32gig. You can use a Navionics East card. Check with your buddies to see which version is best for the lakes you fish.

Here is what I am talking about. https://www.ebay.com/itm/15552659927...3ABFBM6PzJ7pBi

C-Map Reveal does show 1' contours on the HDS 8 Gen2.SD 1-.jpg

I fish mostly lakes in Indiana so if I get this card and throw it in the sd card slot? Anything else to do or does it do it automatically and show up on your maps?

C-Maps Reveal card US Lakes North Central "NA-Y212" will include Indiana. Insert card in SD slot and it will show "Loading maps" on boot up. Then you will get a message if you want to switch maps to NA Y212. Choose yes to use C-Map. You still can toggle back to Insight. Wacky Riggers a good video on how to do the custom shading.

Ok thanks if I purchase the cmaps does the maps show up like the maps on the website with stump locations, etc. 4769031E-092D-48A6-9D29-331873FD3934.jpeg

Stump location may not show on small lakes, but they show on bigger ones. The small ones may have not been surveyed/mapped for structure.

Ok thanks i appreciate it

PM me the lake name and location and I'll see if C-map shows stump location.

Map of Brookville and Hardy. (Monroe has the same detail as Brookville.) I've added the contour shading. Hardy map doesn't show any bottom structure, just contours.Hardy.jpgBrookville.jpg
