Anyone mounted a Zumo XT in place of Garmin 660 on older RTL

[DanY]

Wondering if the bolt pattern for the Garmin 660 mount on my 2016 RTL is the same for the new Zumo XT mount.

Check this out. Google search led to this in about 10 seconds.... https://motogps.com.au/blog/what-is-...-amps-pattern/

No only is the bolt pattern a consideration but also is the contact pin configuration and I don't believe they are compatible with the 660 cradle configuration but I may be mistaken.

The Zumo XT out of the box is designed for a handlebar mount and the pin layout for the electrical connections are very different.

Yes, I understand the pin cradle themselves are very different.

Maybe I’m looking at things wrong but the Zumo 660 cradle is bolted to a mount held in place by the two lower handlebar bolts. If the 660 cradle is removed from that mount, can the new XT cradle bolt back in its place?

Yes I think you should be able to do it. You would need to remove the 660 GPS mount from the bracket (4 screws on the back of the bracket ) disconnect the wires and remove. Leave the bracket in place and put one of these on the bracket https://www.lamonstergarage.com/ram-...all-lamonster/ and adapt from there and wire your Garmin XT.

I would agree. In the generic install instructions both the Zumo 660 and XT, bolt to a standard 4 bolt Ram mount. So the bolt patterns are the same.

Thanks everyone!!!

Not sure what you mean by "out of the box is designed for a handlebar mount". Mine came with the handlebar mount option, but it also came with the AMP 4 bolt base and a plate with the 1" Ram ball mount that bolted to the AMP base.

Getting my Zumo XT tomorrow. I'll be doing the same, removing the 660 mount and wiring and mounting the XT in it's place. Can't wait to get the bigger and brighter screen.

Just started undoing the tupperware and trying to follow the 660 wiring harness to remove it. It seems to be buried pretty deep. Does anyone know an easier way to get to it. I would hate to have to cut it. I had hoped to be able put it back on in the future if I sell it.

If I remember Correct looking from the right side its near the front center of the gas tank. Hopefully someone else will confirm that.

This may be of some help.

Thanks for the suggestions. I ended up taking the mounting bracket apart, unplugging the two connectors, and pulling the wiring harness out of the mounting bracket, Then I pulled the harness back inside the tupperware, and taped it off. That way I can reconnect it all in the future . I'm pulling the XT power connection down thru the handle bars and connecting that to the battery, or a switched source( haven't decided yet ).

You know it can be done if you remove the right side Tupperware and right headlight. Once you remove the right headlight you can see the wires next to the frame steering area. then follow that down and next to your fuel tank.
On the back end of the tank of the right side of the gas tank is the power connector along with the GPS plug.

Its just a bit time consuming but not to hard to get done.

Be careful the GPS harnesses can be easily damaged so test your work before you button up things which ever way you go.
