I have been a fan of *** devices for many years, long before they were in every vehicle. My first was a Delorme device connected to a laptop. It was followed shortly by a Garmin Street Pilot. Right now I use Canon Connect with the R7. I have the GP-E2 and have never been that fond of it. The best *** device I have used with a camera was an off brand of some kind that I put on my camera strap. The device worked fine and what made it best was the software. When you synced it on your computer it usually gave the exact address of where the picture was taken. I think a good *** would be a plus for the R series cameras, the only downside was the power drain they cause.
