Hi, just fyi, on an 19 hour drive from Los Angeles to Vancouver, I've decided to do some experimentation regarding the placement of the Nav antenna (for my retrofitted MCS Nav unit).

1) If Antenna is placed on Roof, it will consistently see 8 satellites.

2) If Antenna is placed on dash in front of Windshield, it will see 7-8 Satellites (you will see the diagnostics info change between 7 and 8 satellites continuously).

3) If the Antenna is placed under the dash inside the air-vent, it will see between 4-7 satellites (changing continuously). This means it will see the 4-7 strongest signals at the particular moment.

Note this was taken along the I5 highway, even when surrounded by trees in Washington State.
