Default Lowrance radar ?

I helped a buddy install his LRA4000 over the weekend. The radar went well but the GPS came up with a lost signal then a GPS not responding message Checked connections turned unit off then on with radar on the GPS came on was working for about 10 min. then lost signal again. The GPS anntina is about 3 feet from the radar and lower by about a foot any thought

Only guessing, but it sounds like you may have disturbed the gps antenna cable connection. First thing I would do is, disconnect the connector at the gps antenna and check the voltage on the #1, (gnd) and #2, (+) pins, (with the unit on).

Check out this link for a better description of the pin location -

If you have an enclosed raydome, and it's 3' away, and 1' above the gps antenna, (as you stated) you shouldn't be getting any interference from it. But... not sure about an open array. You might have to put the antenna on a pole mount and get it up higher than the array.
