NAVMAN ICN 510 v GARMIN I3

[nearly50]

Hello to all. I have just disovered this forum having tried to get an answer on another site forum with no luck. My mind was almost made up and I was going to purchase a Garmin i3 when I found a good price for the ICN 510 for only £30 more. Is anyone able to advise me whether the 510 is a better unit than the I3 and worth the extra. This forum seems to be well clued up and I wondered what the +/- are matching both up to each other. There are so many units about that I don't know what features justify the many price ranges.Any help appreciated.
