I got suckered into buying the 7735 last year because of all the good reviews, and the features. While it may work okay once you get the data entered, it is very non-intuitive to operate and you CANNOT make just a little change while driving! ANY input requires a stop, and go.
We have found the Google maps and apps available online are MUCH easier to operate and intuitive to figure out. If it doesn't warn me of low bridges, I can deal with that for the difference in operation. I would never buy another, especially when free ones are available and better!
