I purchased a CN-16 unit from Opticsplanet. The unit works great right out of the box. Just plug it into the AUX port of the CGE, set up the GPS option on the CGE and you're done. All information including latitude and longitude and real time are displayed on unit. Just two star align and you're viewing. This can't get any simpler. Great price and service.
Pros: Ease of use and great funcitonality
Cons: Would be nice to have LED display on unit but not a standalone GPS unit
