Barry - I've used my VX mount (with C8 on board) with it before...you have to do a star alignment (physically) before SS can take over. Then you just watch the cursor sweep across the display
Regarding SS for Android - iirc when v4 came out for iOS I'm sure one of the disgruntled posted in here a quote from Southern Stars that they would hold a similar promotion when v2 for Android was launched, but don't quote me.
