I'm planning a short solo tour in January that will take me through some suburban and rural areas. My wife is nervous about my safety and wants to know if there is some kind of tracking device she can use to keep track of me while I'm touring. I realize that such a device won't prevent me from a traffic accident or being eaten by a passing bear, but she's asking. If it'll ease her mind, I'm willing to use it.

I was looking at the Garmin 820 anyway. Will this do it? Do I need a website for the GPS to send the information or is there an app she can download on her iPhone?

Thanks.
