As the title says I'm looking for a manual for the euro comand, specifically the NAV functions.

I recently installed the euro nav and got it working. How do I tell how many satelites are being found. I've searched this site and several others and I'm unable to get the engineering menu to come up. I bought the items used and don't know if it was the 2006 or later.....

Is there a way I can find out the software version?

The local dealer only quoted me $80 to connect to the star and disable teleaid, sos and enable the nav.... that sounds too cheap to be true...
