I wanted to start a different thread because this is specific to magnet placement to activate Car Dock mode while using Arkon Mega Grip mount. You can find my original review and pictures of this mount in http://androidforums.com/accessories-droid-x/142370-review-arkon-mega-grip-car-mount-w-dx.html
You do have to play with a polarity of your magnet and flip it one way or the other in order to activate Car Dock mode versus Multimedia Mode. If you look on the back of the phone and imagine a line between Moto symbol and speaker, the magnet placement should be somewhere around the middle right along the line where battery cover is. In the pictures below you can see I used a small round magnet. I just went to the kitchen and ripped it off one of the chip clips. Turned out to be the right height and you will see why. In my original review I mentioned that in order for the speakers to be exposed its better to place the phone with a camera part pushed against the side stoppers of the Mega Grip. Well, it just so happen that other edge of Mega Grip is aligned with where magnet supposed to go. So I simply super-glued it in there. As a bonus it keeps the phone horizontal since a magnet becomes sort of like a spacer on the other edge to even out camera bump.
Just for those who were thinking about taking Mega Grip apart to place it somewhere inside, its not really possible due to all the "guts". Here is picture of inside:
It works great once you glue the magnet on outside. I'm pretty sure Arkon guys didn't plan the size of Mega Grip that way since its an universal mount, but it works out perfectly for our Droid X. Take a look:
