Emap Problems [Garmin eMap GPS - 100354]

I recently purchased an Emap in South America, with serial cable and Mapsource software. The Emap covers the Americas and I have also downloaded specific software for it, successfully. When I initialize it, outside, passing the main agreement menu, the unit does not detect any satellite nor does it give a "Poor Satellite Reception" message. It just show the Kansas standard U.S. Map with a question mark cursor. I think the unit is a Newly Overhauled one, so it might have had some problem before that is resurfacing. Please help!
