Has anyone experimented with using the RAM IPAD yoke-mount system in the rv7 utilizing the windshield frame brace (slider only)? I have my EFB on my IPAD and I'm thinking about getting Wx and TIS using the garmin GL-39 and pilot app. I realize there will be some loss of visibility putting the IPAD up there but I'm getting really tired of what XM is charging me for Wx only (no TIS) on my 396.
