Ok Today the GPS guy came, he told me the unit has very low memory to run the destinator or garmin Gps software, and checked my antenna with no results, he said it's a very bad antenna, and that was probably the cause my GPS is not working, so he is going to get me a new Gps antenna with Sirf III chip, he said it's more powerful and will work, (Hope So!)and I posted some pics of my installation and finnish look, besides that the unit is working ok, I also have some interference noise sometimes, does anybody has that??? I checked the noise filter included and it looked good, but still getting some noise from engine???
