I'm having real problems deciding on a text-to-voice model. The cheapest are Garmin StreetPilot c340 at $199 @CC, the mysterious Invion 3.5" Text To Voice Touchscreen GPS System for $169.88 @ JCPenney, and the Navigon 2100 for $149.99 @ RadioShack. Garmin has the best name recognition but is available for not much over that on Amazon right now, so not that great a BF deal.
The Navigon looks like the best deal based on features, but I'm concerned that the reviews of the Navigon are all based on the specs. Ok, fine, but how does it work? Amazon reviews of the other Navigon models have a fairly high proportion of negatives and many people seem to believe that the company hasn't worked out all the kinks yet. I'd hate to buy the Navigon, find it doesn't work well, and then have no chance to get another deal.
Anybody know what the return policies are on GPS units? I'm considering buying several, testing them, and returning the ones I don't like. Would I be looking at a restocking fee?
