I love my Zumo Harley Road Tech 665 with XM. Like American Express, "Don't leave home without it". I also like wandering around but it's very convenient, when you're not familiar with your surroundings, to hit "HOME" and get there without any problems. The added bonus is having the XM Radio playing thru my stock HD head unit providing me with all of my favorite channels. I have mine mounted with the Iron Aces Road Glide Mount. Can't beat it. Iron Aces is another great company and Forum Sponsor with Superior Customer Service. Great product too!
Nothing else matters!
