When I ordered my RadarBox - OK, it was a long time ago, I was able to follow its progress right to my door :-)
I'm sure that AirNav will be interested to hear your comments and I'm also sure that there will be an explanation. Having used AirNav products for over 10 years now, they have always been very helpful and I wouldn't hesitate to buy from them direct again.
Of course, I am totally biased as you would expect, having been an AirNav customer for all that time, but I am sure that you won't regret having purchased RadarBox, especially with the support you will get here from all the forum members - and AirNav ;-)
