Navman iCN 635 Navigation System,
This review is from: Navman iCN 635 UK - GPS Navigation uk update maps (Electronics)
I have been using this system for a month and I am very pleased with it. I got one just to test it and I am keeping it. As with any product there are pros and cons but on balance the Navman 635 is about as good as it gets. I would have liked to see a full 7 digit postcode search facility like the TomTom instead of the 5 digit search but that's the only weakness in my opinion. What I do like is the robust magnesium alloy casing and the big 3.8" screen with a variable brightness control so that it can easily be seen even when in the brightest sunshine either behind or in front of the car. At night the screen can be dimmed so as not to cause any dangerous glare. Also I like the big control buttons instead of having to prod the screen with a silly little stylus( the unit also has a remote control as standard ).
The voice guidance is very clear with several warnings prior to a junction or roundabout etc. and can easily be heard over a car radio at normal volume levels.
I get 4 to 6 satellites with the internal antenna and 8 to 10 with an external antenna.
The "back on track" (if you take a wrong turn) re-routing software is very good and very fast. I tested it by taking wrong turns into short streets and it always recalculated the route before I got to the next junction which is one of the of the most important features of any navigation system otherwise you have to park up and wait for directions.
The menu screens are easy to access and follow via Menu,OK and Esc buttons.
The box contains the 635 unit, windscreen and dashboard mounts, car cigarette lighter 12v power lead, CD with maps & software, UK maps on SD memory card, 240vac to 12vdc mains power transformer, USB lead, remote control, carry case, screen cleaning cloth and manuals.
All in all it does everything I want from a navigation system.
