Hi,
I have a HB 797c2 as well. I think your software level is 5.450 (you might have gotten the numbers switched around). The Ver. 4 of the Lakemaster LOW Rainy chip is the one that supports I-Pilot Link functionality. There hasn’t been an update on the 797c2 in over a year so that extra file needed to support the “follow the contour” feature (of I-Pilot Link) may be foreign to your (our) boxs. Besides that, the 797c2 will NEVER support I-Pilot Link since we do not have an Ethernet port.
Take care,
Roger
