A few years ago I blogged about locating on off road point on Google Maps. This apparently proved quite useful to a number of Geocachers and ramblers. Recently the Google Maps apps has change on most (or perhaps all) platforms and this hack will not longer work on mobile devices. :-(
The only solution I have found to date is to use the original hack on the Google Earth app instead. Other than using more battery this works well for me. You can turn on roads to simulate the hybrid mode, and I have started saving locations to a map on My Maps and then they are shown automatically on the mobile. I hope this helps (again). If you can figure out a better way then please let me know.
Update: It appears that searching for Lat Long coordinates on there own (without the original hack) will now drop a marker on that exact spot. This is working on the old and new maps online, and the iPhone app, so I presume it will work on all platforms. Let’s hope this continues working from now on.
