With the antenna installed I get maximum signal strength on all bars. Warm up time and connection time is almost instant (used to take about 5 - 10 mins!). I was considering selling my Navman to replace it with another make but with this antenna the device is brilliant. The device seems to be far more responsive, especially when calculating routes or getting back on track. The difference between having the antenna and not is so vast that it makes me wonder why they don’t ship the external antenna with the product in the first place. It really is that good.
Installation is easy. The tiny magnetic box sits neatly behind the bee sting aerial on my roof and the cable can be neatly threaded behind the roof lining so not visible inside. A small length of cable on the dash is all you see. Will never be as good as a factory fit navigation system but far cheaper and can be moved between cars. Thoroughly recommended.

The antenna works perfectly with my iCN 520 giving almost full reception on all satellites. The 5m cable is just enough to stretch from the back of a Renault Scenic where it sits on the roof to the front of the car, passing under the carpet.
However, for anyone confused by the description, the antenna does not use an MCX connector as referred to above but a mini MCX (mMCX) connector as required by the the iCN 5xx product family. Amazon sadly provides no feedback mechanism for electronics products and my report about this by email has not produced any response.

The Navman MCX external antenna for my ICN 550 made a huge difference. I drive Peugeots which have a reflective windscreen causing problems finding satellites.The ICN 550 just couldn't work until I bought the external antenna. Now it starts working very quickly - quickly finding satellites. Unfortunately as good as the antenna is, the ICN 550's screen went into a washed out screen which spoiled my journey as the screen was unreadable.
Would I recommend the Antenna - absolutely.
Would I recommend Navman - not on my experience.
