I would like to integrate a simple ‘route to my store’ using Google Maps MyLocation, for distribution through a mobile browser.
The perfect solution (from the end users viewpoint) would be – A plotted route from the Users GEO-Location, to a pre-configured POI (my store). That’s it. I would like to avoid having the ‘get directions’ dialogue (it’ll look squashy on a mobile device). Just a map with a start point, an end point and the route in between.
I’m not certain that this satisfies your goal of avoiding a “Get Directions” dialog, as it will certain involve an intermediate step by the user. But the dialog won’t “look squashy” on a mobile device; indeed, it will be optimized for mobile viewing.
If you only plug in the daddr (destination address) coordinates to a map call, using the latitude and longitude of your store (or whatever location), Google Maps will try to set the start location to default to the user’s “My Location” position if the device supports it, and otherwise will prompt the user to enter the start location. It will also allow the user to select which of the supported modes of transportation is desired (walk, bike, transit, or car).
This example plots the route from your location to the Martin Luther King, Jr. birth home in Atlanta:

I tested this successfully on the following devices:
Based on the consistency of the responses I got in those tests, I feel confident it would work in most, if not all, scenarios.
