Garmin 62s restarts every time I start the bike - why?

    I mount my Garmin 62s on the handlebars of the bike and have a power feed that comes on with the headlight, so when the bike starts up, the GPS springs into life. Because it also has batteries, it stays on for 30 seconds once you turn the bike off.

    So far so good, but if the GPS is already running (via its batteries, or if I've stopped the bike but the headlight is still on), then when I start the bike the GPS immediately restarts, which means sitting around for a couple of minutes waiting for it to load its maps etc, and hoping it hasn't lost track of the route you just set up before you started the bike.

    Anyone know why it is doing this, and if it can be fixed?

    It's a pain to have to keep the bike running every time I stop to check something on the GPS, or waiting for the maps to reload once I've started the bike. Especially knowing that it will run perfectly happily when the bike is turned off.

    Just a guess but when you start the bike it takes current from the headlight so your gps gets a sudden drop in available power. Why not wire direct to the battery and completely eliminate the problem. I have a Montana plugged into the Merit outlet on the F800GS which runs off the canbus but other bikes I have a Merit socket wired direct with a 10A fuse.

    I should have clarified - the GPS is wired directly to the battery, but this feed gets power when the headlight is going - so when I stop the bike and walk away, the GPS displays a screen to say that it has lost external power, then after 30 seconds it turns off.

    I've had a play powering the GPS off the car to see how it behaves. If the GPS is already on and you start the car, the GPS loses power while the car is trying to start, and displays the "external power disconnected" screen, but when the car starts and it gets power again, it just goes back to whatever it was doing before the car started. This also happens if you unplug the power cable and plug it back in. This is what I would expect to happen when I start the bike, but the bike starting makes the GPS reboot - so you have to sit and wait for it to load all the tracks etc before you get back to the screen you were on just before the bike started.

    So starting the bike while the GPS is running is doing something different to completely losing, then regaining, power while the GPS is running, or the voltage drop from starting my car while the GPS is running.

    Make sense?

    A bit odd! I wonder if your bike is spiking the power to the GPS causing shut down. I think this is beyond my ken and you need an expert opinion. Surge buster of some sort??
