Not trying to knock the radarbox,but the database is not very good.
I brought up this subject last week and i haven't even bought a unit yet. And I won't until it's resolved.
Databases in other AirNav products have not been good and this was a major concern for me buying one. Unfortunately AirNav decided that my message had nothing to do with the RadarBox Forum as it mentioned their other products and so deleted it.
Bit Big Brother like really, screening messages in case it's bad PR maybe
Still, at least they're saying they're trying to resolve the issues. We will see, but the rival is looking better and better at the moment
