about to purchase

I am waiting on stock to arrive as i have preordered and am very concerned about the feedback im seeing on the r 10

do people think this will be improved with an updated firmware for indoor use

This being a new device I'm sure Garmin will tweak the device software until it is accurate. Think about all the other simulators out there and all the updates that have been made to those. You won't find any of them on the original software.
