When using this handheld in a car I understand you can hook up a GPS antenna or it looks like a puk. One is made by Uniden and the other is made by Garmin. This is suppose to enable you to monitor as you move from city to city without having to put in a program. Now does this GPS unit replace the antenna that would usually be used a a mobil antenna or is this GPS puk in addition to the antenna?
