    I wanted to share an educational experience that I just had. Perhaps it will be of value to you as well.

    I recently purchased a new GPS and while scanning through the quick start guide ran across this statement: "Remove the device from the motorcycle mount before connecting a battery charger to your motorcycle".

    I was curious as to why, and asked numerous others for their thoughts. I even asked a dealership representative. No one had ever heard of this. I have previously used GPS's for years and had never heard of or done this.

    My unit is a BMW Motorrad Navigator VI, made by Garmin. So I contacted Garmin Tech Support with my question. This is their reply:


    Hello Ray,


    Connecting a battery charger to your motorcycle while the device is connected can cause too much electrical current to be provided to the Navigator resulting in a device which no longer functions.



    Thank you for choosing Garmin,

    My previous units were earlier BMW Navigators and I never had a problem; however, considering the cost I will follow the recommended procedure.


    Hope you find this informative.

    New info to me.I'll check my Nav VI manual.

    I have connected different chargers direct to battery on my prior 05 GS and current 14 GSA with Garmin Nav IV,V and now VI connected,no apparent issues so far.

    Maybe they mean avoid charging that involves the ZFE circuit,such as with the BMW battery chargers.

    That is what is known as BS.
    A battery charger on the bike with the gps attached is a non-issue.

    I think you are probably right. But it is not totally implausible.

    Not an issue for me since I use my GPS power port to charge the battery.

    And I would never (intentionally) leave the GPS on the bike for any length of time when not using it. They seem to draw enough current to drain the battery even when off.

    Definitely.... gps's are insidious about parasitic draw if not connected to a switched circuit. Lots of folks like to keep gps running during meal stops so the attach to battery directly. I use a neutrino black box and leave circuit live for 1/2 hour or an hour. Best of both worlds
