i really like my garmin because i'm an investigator and have to find specific addresses. I just put it in and the prompts get me right where I need to go. I have mounts in both my car and on the bike and use sound suppressing ear buds on the bike. I have loaded most of the NE United States onto a card I can add to the unit which gives me every street in PA, VA, DC Maryland, WVA, Delaware, NY and MA. I also have an mp3 player on the unit which allows me to download music from my computer, it also serves as an address book, and note pad. The only drawback us that the IQ 3600 is not waterproof so i don't use it on the bike in the rain. This doesn't mean I still don't like maps, I do as well as just wondering around lost on purpose.
