Thanks for the update on the XM weather sharing through interlink, I hope that is true but I have read conflicting information in other threads, not doubting you.... I also understand from reading in other post areas as well as my own IT background, the increased capabilities and speed of ethernet. What would be helpful for us and for Hummingbird to consider, which I'm sure they already have, (and you can't tell us if they have or if they haven't... smile), with the unit having two separate communications systems it will be challenging for the consumer to pick and choose which options are most important to them because different accessories and or unit functions are shared thru the different communication mods. Perhaps the different paths are specific to the type of data but at a minimum, if all features cannot be shared through one or the other communication mod, a more user friendly on off function would be desirable to the plug unplug requirement. I say this because I am one of those consumers that may want, and be willing to pay for, any and all unit features as long as I can transition to their sharing simply - Again thank you for your feedback
