Does the 130 support cue sheet message for turn-by-turn? For example, if I create a TCX map in Ride With GPS (along with associated cues) and upload to the the unit, with the cues show up with the turns? (e.g., "Turn right on Sawmill Road" along with the right arrow icon?)
I don't know if the .FIT file type supports it. I never tried. Fact is the 130 does not support anylonger TCX and CRS. So hopefully somebody else have tried this out. Please be careful with the 130. Don't expect anything working by experience with other Garmin devices. They have decidec to put most software restrictions ever to this device. And I would recomment to read the battery life thread. Just to ensure no suprises.
It does not have a separate course point page listing, but it will report the the next course point in the "Location at Next" data field.
Course points can be defined in both TCX and FIT files. The 130 does not import TCX files therefore you need to use a mapping site that either supports exporting your planned route as a FIT file or you need to run the TCX file through a converter to get it in to the FIT file format.
There is an earlier thread on how to do this conversion.
