Solved my Signal Strength Problems,
Verified Purchase(What is this?)
This review is from: Navman MCX external antenna for iCN 5xx (Accessory)
I was having problems with Signal strength and reception with my ICN 520. This was due to the Ford Heated windscreen in my Car. The external antenna has transformed my reception getting nearly maximum strength and reception. Recommended if you are experiencing problems with Signal Strength.
