I have a couple of questions. I heard on another Titan forum that someone says the Titan has speed sensitive wipers when on intermitent mode. Is this true? and also What is the small grill that is located under the 4wd selector switch or blank in a 2wd case? Is it the ssv microphone or what? It's probably about the size of a dime.I'm sure it tells what it is in the manual, but don't have it with me to look.
