Hi dbhelix, I read your words with great interest, mine were not expressly directed to you.
I understand that in the US nyon is not supported, although and probably if one item is not sold in my country I would not do any strange rounds to get it but I would focus on alternatives, as you did with cobi. In any case in europe the nyon is sold, supported and still works great and better than any alternative.
But let me better understand this thing of your lost data, deleted by whom and how? and what features would be limited or suppressed and how it relates to the loss of personal data on bosch's ebike-connect portal?
I (and bike shop who sold my R&M) have updated everything quickly and without hiccups, no loss data at all.
Maybe it's me that have not understood because of my poor english: the mask to which you refer of the nyon what part would it be? an aftermarket accessory or an original part of nyon? because I have no mask that can detach or pop away from the nyon, it feels like a solid, well assembled unique piece that, as you well know, applies exactly same as intuvia. Can be that your nyon was defective and not well assembled?
Concerning import of gpx data you can also create long tours and import them at once before leaving home. Or import it splitting the route for day by day use. Personally, when traveling for more than a weekend i carry a tablet with me for other reasons so I have no problems to do this operation during the journey. I suppose you can do this also visiting ebike connect portal from a smartphone. In any case it is not mandatory to import gpx data created by other platforms, you can use directly paths created by nyon at the moment, ok also the fast route tends a little to the offroad but not so much as not to be considered reliable. in short, I do not see it as an insurmountable problem, and you would still have this same problem using any alternative to nyon.
But, like you said, Nyon in US is not supported so i feel to fully suggest it just for users that lives in country where nyon is officialy sold.
