I believe I was reading a review of the 340S a few weeks ago and someone mentioned that you can un-install (delete) languages. Given the fact that I'm obsessive compulsive when it comes to my digital world, I'd like to streamline my device by removing all the languages other than English and the Mexico map. Can someone kindly post instructions on how to do that? Secondly, do the TomTom map updates ever go on sale, or is the Map Share sufficient in most instances? Thank You!
