Long shot here… I’m trying to track down a usb cable for my old (no card slot) helix 5, & they seem to have gone the way of the dodo. Humminbird hasn’t been any help & I haven’t been able to track one down at a retailer/eBay etc. Any chance anyone’s got one kicking around they’d be willing to sell me?
I found a used one on amazon a few years ago, used it to install the last firmware ever released for the Helix 5 sonar, then returned it back to amazon. I’ll keep an eye out for ya…
Looks like there’s a newer part name for the full kit – AS PC3 – Advanced Accessory System PC Connection Kit
