Honestly, it was not clear for me what @moonlight wrote.
I am a bit disappointed after years of using more map extension by JA.
None of them were working out of the box nor the documentation was accurate enough for any low IQ user like me. The result always arrived by extra coding of your stock file with or without your help.
Well, back to this current issue... Even I modified the plugin parameters, even created a module with new parameters, even added the parameters to the contact's misc. info. the result was not shown.
First of all the ability of setting the zoom level would be fine.
