Has anyone else noticed any issues with their WAAS GPS = installation?

I just convereted a 530 and 430 to 530W and 430W. My GPS antennas are on a tray just under the glass section in front of the = vertical stab on my IVP. Since I got Waas I get "No GPS navigation - = user other nav" message. It happens on the ground, it happens = whether near buildings or not, it happens to both navs but at different times. It lasts from 30-45 seconds = typically.

One theory that has been put forth is that the WAAS units look further down = the horizon (or need to to get a big enough constellation) and that I may = have some blockage at those low angles. So far I haven't seen this = happen in the air.

I also converted my cessna 530 to 530W. I haven't = noticed any issues. The antenna is OUTDOORS in that = installation.
