The base sits squarely in the tray above your nav unit.
But I have an HDS7M
That's what it sits there perfectly
Just screw it to your dash.
In your pic I couldn't see the border of the GPS and I thought it was flush-mounted. I assume now you're using a mount similar to mine.
I replaced my Lowrance Elite 5M Baja with an iPad Mini w/Retina last month. I looked at the HDS7M Touch - a very nice GPS! I thought it would be cool to have the ability to use the iPad for multiple purposes, instead of just GPS.
The Baja worked perfectly at TRR last year. I will find out this year if the iPad with MotionX GPS works as well. I'm concerned the GPS won't be as accurate. There is an option to add external GPS to the iPad for better accuracy. If it doesn't perform well enough, I'll switch to the HDMS7 Gen2 Touch.
