Okay, finally had enough of struggling with traffic and maps. This weekend we were coming back from Portsmouth to London and the journey took around 3 hrs. The upshot of this was that my other half is convinced that we need a nav system. The one we're thinking of going for is the Alpine 1-Din system, but I don't want to spend this kind of money and then have it installed by somebody who doesn't know his posterior from his elbow. Can anybody recommend a good dealer (preferably in London) for installing this stuff. Also, if anybody has any experience with the Alpine navi gear, I'd be interested in your comments. Thanks.
