Sat navs: Compare features & prices Garmin nuLink! 2390 review http://www.which.co.uk/technology/computing/reviews/sat-navs/garmin-nulink--2390/review/

Having graduated from Navman to Garmin my first model was a 310. I then upgraded to a 765 which, after 4 unsuccessful units I selected the 1390 as a replacement. This was not without its glitches and was also replaced 3 times.I was then faced with either paying for a map update or choosing a "modern" unit so I chose the 2390. This is the first time that I have elected livelink technology and I couldn't be more pleased (unless the lovely guys at Garmin could reduce the subscription prices).Three is very little difference from the 1390 model in terms of operation and there are certainly more features. I do make good use of the live traffic cameras given that I use the same route via the M1 in South Yorkshire 5 days a week.The traffic information is very good although the fact that traffic sensors are occasionally out of order mean that the unit reports delays that don't exist - but that would happen with any unit. I do like the fact that the unit reports alternative routes and anticipated time savings. What I would like even more would be for them to be audible alerts.I also subscribe to the fuel price updates which certainly pay for the monthly charge several times over. I have also chosen to subscribe to the Advanced weather service which gives good coverage of the driving conditions over the most recent hour and allows you to better plan your journey.The ability to add waypoints to your journey is also a very useful feature of this unit.There are two main drawbacks to the unit's operation. The first is where the speed limit indicators are incorrect. I have noticed recently that speed limits travelling in one direction on a particular road indicate 30mph in a 40mph zone whereas the same length of road travelling in the opposite direction displays the correct limit. To counter this the fact that nulink updates temporary speed limits on motorways in roadworks sections is a welcome addition (although they don't always remove them after the roadworks have finished).The other, albeit minor, drawback is that the unit always overestimates the journey time. My work journey usually takes an hour, give or take three minutes. The nuvi 1390 always reported the correct time whereas the 2390 starts off at 1 hour 17 minutes and reduces the journey time / eta as the route progresses.Overall the benefits outweigh the minor niggles and I would certainly recommend it.
