Their customer support is actually quite good said I speaking from experience. The fact that I have had a huge amount to to with them is not good.
I have the Pacific Islands and Australia on both my iPad and iPhone and also have the same chips for my Lowrance so have spent a motza with them. I went to update my chips on the Lowrance which I had never done before, my fault, and they became corrupted. Fortunately I had evidence of purchase but still had to fork our over $300 for replacements. I know now to keep the bloody things updated.
The issue I have had is with Sonarcharts. I purchased a Vexilar T-Pod to attach to my Kiteboard so I could update some of the reef entrances that I use. All Fiji maps are bloody hopeless. you have to follow the rule "in after 10 and out before 4" because visibility is critical. The last survey was done when Captain Cook was a gleam in his dads eye and a lot of the information is based on aerial photos.
Anyhow the T-Pod turned out to be incompatible with Navionics. If you look at their advertising now it is quite clear but when I purchased it it was not. Long story short, I now have a T-Box portable which will fit in a dry bag on my back but now I cannot get Sonarcharts Live to operate. It displays a message saying that the sounder is not connected but on the same page in split screen it shows the sounder readings! Go figure.
Here are a couple of screen shots I took from a downwinder I did on Sunday
I ran out of water right at the end. I was kiting in six inches and the coral was making awful noises on the bottom of the board. I had to walk the last 200 meters!
