Thanks David. When I go to settings > base stations it says 1.0. I purchased the original HTV Vive less than a year ago at the same time as the HTC Vive Pro, so that I could steal the base stations from it, since there was no way to buy base stations at that time.
From the other thread I just read HTC doesn't do advance replacements so if I can buy them on their own I'll just buy a new one. Not worth the trouble to ship it back.
Can I mix and match version 1 and version 2 base stations?
It looks like the only base stations being sold now are 2.0. I'm reading some contradictory info on this - but it sounds like the correct info is that you CAN combine a 2.0 base station with a 1.0 base station with no compromises? I'd like to order one of these.
