On every GPSr I have ever used (except Magellan) when using imperial units and navigating to a location the target distance is shown in miles until the target is closer than 0.1 miles away, then it switches to feet. AQ gives this distance in feet once the target is closer than 1 mile away. I find this difficult to use.
For example, 3690' is not very helpful to me and I have to go through the process of mentally trying to work out what fraction of a mile that equates to, whereas 0.75 miles is much simpler.
Would it be possible for you to make this change?
