Have just released googleMaps module v3.0.1 which works with the latest Joomla 3.4.3.
For Joomla 3.4 and higher, modules that have capital letters in their elements are now forced to lowercase during module installs (as a result of some standardisation in the installer). This results in case sensitive systems with the XML file being unable to be found. Details here.
Have renamed all googleMaps to googlemaps, and everything now works.
Special thanks to Matteo for informing me about this.
