You Lie

I bought myt delorme from their website. flew to california to buy a car and used the gps to drive back. I lost signal in nevada,colorado,nebraska, ohio, and illinois, all during a rain. IN DIFFERENT STATES! On normal days it catches every signal, but on rainy days (i'm not talking about drizzles, i'm talkin about RAIN) can't get a signal, and i live in chicago mind you
