Thanks Wayne it worked great download complete !!!:nanner:

I downloaded this update to adobe acrobat reader dc and then to a micro sd card. The card does show the update on it but will it download to my helix 7
I don't want to mess up my unit if this does...

Thanks Wayne :thumb up2:

I know that hummingbird makes a trolling motor broad beam 200/83 khz for this unit but i don't see a transom mount. I use 83 khz to find fish and the unit only comes with the 200/455 narrow cone...

Got a Helix 7 chirp DV GPS G2 for Christmas I struggled between the Helix and a Garmin but Humminbird won out !!!! :nanner:

Thanks guys i have a new 16 GB so it is more than enough.

To do an update what is the maximum amount of GB needed in an SD memory card ?

Thanks Wayne

I know this unit supports DI chirp but does it also support 2D chirp from the supplied transducer that comes with the unit ?
