Short answer: your options are DIY fix or buy a new Garmin.

Thanks for digging that out, DIY bodge it is then!
Mine is just left on the turbo and turned on with a pen or something. I have other units for outside. If anyone does a batch of 3D printed buttons I'd probably grab one and try a repair but it's not a deal breaker for inside use.
