For four years now, I've been using my Zumo 665 with XM radio, traffic and weather all the time, but especially on tour. When I bought the Trophy, I didn't even activate its XM, since it doesn't provide any weather radar or traffic data. Traffic in my area isn't much of an issue, but weather certainly is and I really like having the ability to see how my route may intersect with bad weather ahead. The Bluetooth link between my Zumo and my Sena 20S headset lets me clearly listen to music and the turn-by-turn directions.
