Pretty good if youre patient
I am currently in CR. First impression of app wasnt great. In taxi to San Jose hotel, loading hotel as destination for POI caused app to exit every time (La Rosa De America). I rebooted iPhone and ran app by itself, then it settled down. Has been working fairly well. Still may exit after choosing POI, but generally is OK.
POI database needs more entries but its adequate for most tourists. Road database has many lesser roads but not the one our hotel was on. Navigation generally worked fine once the route stayed loaded.
Will get better with some more work.
Altitude would be nice to have in the mountains driving through the clouds.
A week later ... Not as positive. Maps really need town names. Database needs more POIs. App needs to crash less. Went through Playa Jaco on trip from Monte Verde to Manuel Antonio and app tried to direct us off main highway through town roads then back onto highway.
still pretty rough. Keep trying guys, it has potential. If I were starting another trip I would still use the app but you really need a paper map, a navigator and some common sense when interpreting the app directions.
