That's what I do to............ I think the map download was 10 bucks..........I have spent way more than that on way more useless stuff.
If you have a smart phone that would mean one less dodad to take with you.

gps eats phone batteries.

I keep a phone charger in the boat at the helm........ I keep the iphone connected to charger.

What problem do you have using the etrex? That is what I use .

You don't have to leave your phone "ON" all the time. Mine goes into sleep mode after 1 minute saving battery. You don't need to have the app open all the time. Only when you are navigating.

Look for 1 second updates on gps.
