Hi, this bug could use more information in your report https://bugzilla.mozilla.org/show_bug.cgi?id=992537

Also it seems the feature is no longer available? https://groups.google.com/forum/#!top.../RC0WfW-BGXc

I'm also encountering the same problem with Firefox 28.0 under Windows 7. Note that this bug refers to the old Google Maps interface as the "Send" feature has yet to be implemented in the Google Maps redesign.

In the old interface the "Send to car" dialog box appears as normal when you click on "More" then "Send" then "Car". The pop-up window is populated correctly with the new location and my account data from the last time I used the feature (I'm sending a location to a Nissan car). Clicking on the "send" button at the bottom of the dialog should post the data to the car's information account (e.g. Nissan Connect). In FF28, it does nothing. The only way to clear the dialog box is to click on "Cancel".

Note: The "Send to car" function is still available and still works correctly in Chrome Version 34.0.1847.116.

Update: Still broken in Firefox 29.0.1.
