I purchased an elite 7 hdi unit to put on the front of the boat.  I purchased from a friend who won the unit in a tournament.  I was reluctant to buy it because I am a humminbird guy.  He sold me the unit at a great price.  Since using the unit I have really liked the unit.  The sonar and down scan does a great job.  I am able to mark fish and catch those fish if the fish are set up on the structure the way I like.  

 

Recently I was asking about a Navionics card for this unit.  I thought I was going to buy the Navionics + card, however, I purchased a Navionics Premium card. I wanted to have a good Map so I can sit on a certain spot offshore.  In the past I have just turned my humminbird around and use it.  However, having a unit up front is the way to go.

 

The Problem:  Since installing the Navionics card the unit takes forever to load the map when I zoom in.  If I zoom from 0.5 mile to 0.1 mile it takes about 5 seconds to load the map.  The time increases as I zoom in.  If I zoom down to 50 feet it takes 30 seconds to load the map.  If I zoom all the way in to 30 feet scale it takes 32 seconds to load.  I like the zoom to be pretty close if I am fishing offshore and trying to stay on a waypoint or at least close.  It did not do this without the card installed.  

 

 

I also put the navionics card in my Humminbird 798 and increased the zoom all the way in.  It took less than 2 seconds on each zoom level.  I was checking to see if my card might be bad.  I even took an old 2010 card and put it in my Lowrance to see if it would load faster.  However, it still takes forever to load.

 

Is this a processor issue?  Software issue?  I do have the 3.0 update on the Elite 7. Is there something else I can check before I contact Lowrance?  

 

Thanks

I had the same unit. It does take a while to load the map pic when zooming in. I believe it has to do with the processing speed. I ended up upgrading to hds gen 2 and night and day difference. It take 1-2 sec and the maps uploaded.
