Are you sure about this ?

Not so much the location of the antenna, as the reliable 15 seconds lock time.

Sure you simply did not get a hot fix after having just recennly disconnected ?

I have it mounted vertical in the car and it can still sometimes take several minutes to get a lock. Though excellent at keeping the lock once it has it. It is 15 seconds sometimes.

One concern I have is how it will behave on a hiking trip I'm planning. Don't want to keep the thing on all the time, since battery life is an issue. But I also don't want to wait around for several minutes to figure out which way to go each time I start the app.
