Just back from Halfords (trying to make a decision on which to buy!) and although the salesman steered me towards Garmin, he didn't try and put me off the 4350max, he did however say that Navigon 4350max is excellent value for money at less than £170, but then went back to taking about Garmin
I did a demo whilst there on first the Garmin 765t, very easy to use but I didn't like the layout and screen graphics much, found it to difficult to see the information easily.
Next was the Garmin 1390t, i thought it was slightly better than the 765, but only the screen graphic's, very similar, maybe even the same but somehow seemed better!
Lastly I tried the Navigon 4350max, not quite as easy to get around the menu's as the Garmin's but still pretty easy.
I liked the layout more than the Garmin's, much easier to see at a glance all of the information on the screen, safer when driving IMHO, although to be honest, I did find it a little 'old fashioned' the 3D screen display was more 2D, but still a nice unit.
These are the thoughts I relayed to the sales guy, he didn't disagree but still tried to get me to buy a Garmin.
I'm still undecided as yet, both the Navigon 4350max and Garmin 1390t meet my needs, oh what to do
