New unit and went to soccer field just to do the settings in go4 (cant do inside, i live in a mobile home) and it said updates were required. Manual said i could do both AC & remote at the same time, but all the remote would do was cycle thru modes. danman32 said they had to be done separately, so i followed directions and connected AC to computer by itself, but when I signed into my account, assistant only showed a circle with usb with arrows pointing to a laptop. Tried different usb computer ports but the same result. Formatted sd card in the same ports & all good. The cable for the remote & AC is good cause it charged the remote. Anyone know what I'm doing wrong. Very frustrated and could really use some help. Thanks.
