Title: Unit not reconizing gps
Post by: Foster78 on June 11, 2011, 12:56:05 PM

My unit is not reading gps. Is keeps saying no fixed postion and no temp reading or left side on side imaging. I reset defaults and still nothing. And I have a code 621sm.  Unit is a 987 Thanks

We could use a little history.
Was it working initially? 
When did it stop working? 
Have you changed anything before it stopped working?
Have you tried disconnecting and reconnecting everything to insure you have good connections?
Is there enough voltage going to your unit?
What is the layout of the equipment?

George

My unit was showing the unit was connected to gps but was showing no fixed position. Temp was not working and half of the side imaging either.

Is that code on your map page if it is that is your zoom. Take it in or out.

I would guess that when you set defaults the temp reading was lost....glad you got it back.
Something still wrong with gps.  err of 651 sm it way too high. 
As Gary asked,,,,can you swap the unit.
