I purchased the Astro 220/DC30 in May of 2009 for my Samoyed who if you have ever owned a sled dog (Samoyeds, Huskies, etc), you know all too well their fondness for roaming, chasing, and running all the while forgetting to listen (ignoring is more like it!) for you calling them!
I now feel extremely comfortable when my dog is off leash on hikes, as the Astro 220 does as advertised. I know whether my dog is on the move, treeing some sort of critter, or resting. I also know what direction she is located and approximately how far away she is. It's also come in handy finding my way back to the car a couple of times.

i just picked up one of these for a nuvi 750 as the case is listed as compatible on the garmin site. stylish looking case however, the 700 series is thinner then 600 series. if you hold the case upside down, the nuvi will fall out. be caareful.
