So I'm looking at a Giant Stormguard that features the Giant RideControl Ergo 2 controller and the RideDash EVO display unit. I also want to use my Garmin Varia radar on the bike, but I don't want my handlebars to look like they're something out of an A10 cockpit. Id'd like to get everything on one display with a unified way (the Ergo 2) to navigate between functions on the display.
My LBS is absolutely no help in this area...they barely know what the RideControl/RideDash does. What I'm wondering is if it would be (easily) possible to totally ditch the RideDash display in favor of say an Edge 530? It seems like this would consolidate all the features (Nav, Radar, bike info, etc.) onto one screen while using the buttons on the Ergo 2 to move around between functions.
Am I looking at this the right way? Because if not, it seems like that I'd be stuck with two displays with a lot of overlap in features.
