Wonder if it would trouble the warrantry? Maybe if the dealer installed it? I'm thinking they would not care for add-ons. BTW, this truck monitors a lot like that, exact water and oil temp/pressure. A host of other crazies. You can text and email by voice. Silly really, it just came with it.
This device sounds great as long as it's pretty user friendly to operate and the dealer oks's it! ":-D
