I asked this question on another forum, I'm hoping to get some answers from you guys as well.

I bought a new Lowrance Elite 7 HDI with latest update(1.8). Unit will not turn on with navionics gold card inserted. If card is removed, then the unit turns on immediately. If card is reinserted then the map shown is very basic, almost no detail and only a portion of it is displayed.

Has anyone else had this problem? Does the card need to be updated? any help is appreciate it.
