I already spent the $40 for the oem mount.... I'm looking at a Velcro solution for now I think and maybe a battery tender with usb to charge it... That make sense ? I'd like it to work like it did in my car .... Turn on with power and shutoff with power
Don't think a battery tender charger can be used as a 12 power source but you can try.
Battery tender is a smart battery charger that turns on and charges, then turns off and test to see if additional charging is necessary. Don't see that working very well as a 12 power supply but it might work. Then again, it might not and it might get fried or fry your USB charger.
If you want to hardwire it to the bike so it stays hooked up to the bike, buy a USB adapter connected to a switched DC source on your bike. Lots of folks use the taillight circuit to turn on and off a relay that connects to the usb positive to the battery positive only when the taillight is on.
When you say Battery Tender, are you referring to the type of connector the Tender uses (SAE)?
I think the best solution would be to hook up a USB port to the Accessory outlet/connector that Yamaha already provided behind the right side fake air scoop. There are how-to's about this around here somewhere I think.
I don't know how much I would trust Velcro to secure the GPS unit though.
Sorry for bringing up an old thread, but I am about to purchase the OEM mount but before I do, I just wanna see what the mount looks like without the gps on there. Can anyone who has the OEM gps mount post up a picture?
