Long-term Review: Garmin Zumo 220 GPS

I have ridden my 2007 Suzuki V-Strom 650 with a Garmin Zumo 220 GPS several thousand miles, through all kinds of weather, over the past year and have a follow-up long-term review.

This unit has been up into Canada with me and around Washington, Oregon, and California. In that amount of time a few issues have cropped up, one of which has proven to be very inconvenient.

Because the unit doesn’t snap into a connected docking station, I have to plug a mini-USB cable into the back of it before mounting it into its cradle. This doesn’t take very long, maybe 15 seconds more than it should, but that’s not a big deal. The problem is that when I’m stopped, even if I turn the unit off using it’s power button, it still draws power as long as it’s plugged in. I forgot to do so on two different occasions and both times it completely drained my battery within 36 hours. Fortunately both times occurred when it was parked in my garage at home. If this had happened when on a big trip the inconvenience would have had me tossing the confounded thing into a ditch or against a brick wall.

I had my local motorcycle shop rewire the power cable so that it was integrated into the ignition switch circuit. Theoretically this should have disconnected power to the unit whenever the ignition switch was off. However, this doesn’t seem to be the case. Regardless of how I wired the unit, if I power it off with its own power button, it should halt the current draw and protect my battery charge.

On a recent trip to Canada, I also noticed the unit would spontaneously reboot itself while I was traveling down the road. There was no obvious cause or trigger for this behavior. Fortunately it came back up after a few minutes and it maintained the route I had programmed in it at the time. However, this is an unnecessary distraction and a potential inconvenience. It also makes me lose faith in the unit’s reliability.

I am currently researching a new GPS unit for my bike that uses a docking cradle rather than a cable. I will also verify the power cable is in fact disconnected when the ignition to the bike is in the OFF position. If anyone knows of a unit that meets my requirements, please post the make and model in the comments section.
