340 vs 330 vs 320? i'm considering purchasing one of these 3 units. the low price of the 320 is attracting me, but the text-to-speech feature of the 340 is also good. is anything in the 340 really worth spending that much more money for?
It's just my personal opinion, but I don't think text-to-speech is worth that extra money. For one thing, the machine pronunciation can be very easily just wrong or weird. And most of the time, you don't even have to care about the street name when making a turn, as you can see the turn clearly on the screen, as a big nice arrow. So you don't have to keep reading street signs to not miss a turn. Street signs are quite often very hard to find and/or very small to read, right? Text-to-speech would help only when the street signs are easy to find and read.. If you want to know the street names, you can read it on the screen.
I think Text to Speech feature is a great feature - not to be taken lightly. Sometimes the delay in the GPS processing and closeness of streets confuses you. Also, closely situated exit ramps make GPS direction 'Turn Right in 500 feet' is ambigious. Spelling out the Street name or Exit name removes the ambiguity. It is good that Garmin is bringing out this feature on their C series.
In fact, I was quite disappointed not to find it on MS Streets. Of course C320 in this price is unbeatable. I have bought one C320 and planning to get another one for my wife but I would rather wait and get C340 when it is under $400.
It's VERY simple. If you are even minimally computer and web savvy, buy the C320, load your own maps and save a few $$$$$. If you are computer deficient or unsure, buy the C330 and it will work right out of the box. Later, if you gain the computer skills, you can use the SD card to add your own POIs (points of interest)from the web. Don't bother with the "spoken streets" feature. It isn't worth the cost difference and the street names are VERY legible on the display.
