I’ve seen on eBay that you can buy a usb satnav upgrade but I’m not sure if it’s for your year or the earlier models with the navi 600?

Hi I’m hoping someone can please help me. I’ve got a insignia ecoflex elite nav and I’m trying to hardwire my dashcam, I’ve looked into the fuse box and the fuses I’d need to piggyback from are already being piggybacked, but I don’t know what for??? Any ideas? Thanks
