Just bought a new boat with Hummingbirds, always been Lowrance. Currently have a Helix 12 Mega SI+ G3N. Current software version is 2.180. I bought a Lakemaster Premium VX and instructions say software needs to be 2.720 or later. So I bought a new micro SD Card, 32 GB, speed class 10. I formatted the SD to FAT32, then downloaded the earlier version of HELIX12CHIRP_MSI_GPS_G3N_V2_280.bin (latest version is V2_930). I installed the SD into the unit and I get the prompt asking if I want to update from 2.180 to V2_280 and next window to confirm. I confirm yes to both prompt windows. Then nothing. I have let it sit for 20-30 minutes. I have tried both SD ports. I have confirmed the .bin update is on the SD card. I still get nothing after I get the window asking if I want to update.
I have tried to go from current version to V2_930. I don't even get the prompt windows when I try this route.
I have called tech support and supposedly they are closed due to internet outage.
Please advise.
Thank You,
