There are actually some pretty cool features available with these if you look around.

You can get some that come with wireless reverse cameras that use the GPS as the monitor, blue tooth handsfree, ability to play video files (which is good if you have small children).

I have Navman and also used a tomtom for a few years. My next one will be a chinese one off ebay that has much more features than the brand name models for half the price. Ebay has hundreds of them.
