Will antenna help?
What is your car brand & model?
I ask, because some vehicles use a thinfilm windshield heater for defrosting/de-icing. This file is conductive, and will act as a shield to the RF microwave signals that GPS operates on. Consulting the owners manual, or the car dealer could help determine if this is your case.
Please try the unit outside the vehicle (in the same location as you have troubles) and see if the issue resolves itself. If so, then yes, using an external antenna can resolve the issue, but it will need to be located in a place not covered by that same problem.
All GARMIN external antennas are waterproof and have a very thin cable, so it could be located outside the vehicle. Alternatively, a side-window mount for the antenna could be used, if that's a viable solution in your application.
The "less-expensive" antennas mentioned can work, most will, but you may not get the optimal performance as one designed specifically for the GARMIN units. Personally, I've used an afermarket one and had good results, but the GARMIN ones always seem better.
