No doubt ChristoHD you have done a lot of work and your posts are very helpful. Have you even looked into TYRE.

 

Thank you Cowboy! :-)

Based on your post, I plan to later today! :-)

 

Not to get off topic here, but which Zumo do you have? The problem I have in carrying mine on the bike as a back up (or in the car for that matter) is in the manner to power it with the vehicle's 12V system. On my model, the external power source is through the mount. That is different than the automotive GPS units, where there is an external USB jack on the case somewhere. The only USB connection on mine is behind the battery cover which must be completely removed for access. Is yours the same?

 

I have the Zumo 550. It came with car cradle mount and a motorcycle cradle mount. The motorcycle mount is a RAM mount, and then I bought the cigg lighter adapter for the motorcycle cradle mount so it keeps a charge.

 

Correction - so it was SUPPOSED to keep it charged - but for some reason when I plugged it into the either the trunk or the fairing power outlet, it did NOT charge, so I am looking into that this weekend. My bad, sorry for the initial incorrect post. :-)

 

Bummer - Windows only. :-( So it will have to wait when I can get to my laptop later where i have Win 8 emulator on it.

 

ChristoHD thanks for all your work in this thread. I've learned allot.

 

Mine also; I guess I was incomplete in my post (sorry) - do you have the motorcycle mount clamped to your handlebar? I want to avoid that; because of the Zumo mount design with the bundle of wires coming off the mount itself it isn't easily removed from the bike when not using the Zumo GPS. I'd like to use it ONLY as a back up; possibly using a set of ear-pods plugged into the output jack on the left edge of the unit. But to do so, you cannot power my Zumo with the vehicle's 12V power & must run it on the internal battery unless you remove the battery cover. Is yours the same?

 

RickLB - my pleasure, the nerd in me loves this stuff! :-)

THANK YOU for your service, so I could have the freedom to be a nerd! :-)

 

Yes - I have RAM mount/ball attached to my brake side assembly -
I just have one sleeved wire that comes from the cradle to a cigg lighter end. It works on my 2010 FLHP where I installed a mount power combo. But because (I think) how the 12V is wired on these (usually the positive and neg are reversed) it won't work.

Cradle assembly -

Cradle power wire -
I have no other wires other than that power cable for the Zumo cradle - and with this set up I can remove the whole caboodle if need be.

HTH?
