I'm actually familiar with iGuidance, I was looking into it years ago when weighing alternatives for my Pocket PC (before the era of all PPCs being phones).
The reason I didn't buy it is that Mapopolis had the same features, including Text-To-Speech and more updated maps than Tom Tom, but was a fraction of the price.
Now that Mapopolis is no longer in business, I'm re-evaluating Tom Tom. To be honest, years ago Tom Tom's maps were the worst of the big GPS apps, but as of recently they are using the same map source as iGuidance, so the maps should be just as accurate.
The only thing I'd be losing by going Tom Tom is the lack of TTS, which coming from Mapopolis *IS* something I'll miss.
However, iGuidance is still on the expensive side (about as much as a stand alone GPS unit would cost!). Therefore, back to Tom Tom and my questionable ability to purchase maps.
To be honest, after downloading Tom Tom home, it looks like I CAN purchase the US maps for the version 7 it detected on my phone.
Still, since only one person seemed to know that, I wonder how many of us here are using legit maps...
