CF gives you ability to at least take a look... maybe it would be good idea for FLUX to also provide a GPS track file (for GPSGate or something) of a route on maps they include in demo, so user could take a look how navigating works...
Hmm... then is there a refund option if the GPS is not good enough?
No. But I am sure you can look around the forums for people and ask them questions you have.
If you decide to not go with Destinator, then you can get a trial version of iGuidance v4 for $4 to $9 legally, and I think there is even a CF plugin for iG now too.

Unfortunately, it's just not possible to provide demo maps of the whole world. I'm sure you all will understand this.
I can say this though, from the support emails I've read through in the past few days, the time I've spent on the forums ramping up for support, as well as my own use of Centrafuse, MANY customers are VERY happy with the navigation and the maps used within Centrafuse.
