Thanks for taking the trouble with a full response, but I've come here from the Xtail owners' club.

So far no update DVD has been produced for the Connect Premium HDD system and there is no sign of one on the horizon. This is pretty annoying since update DVDs are available, from the source you mention, - in 2 varieties - for the DVD driven system. These don't work for the HDD system. So the newer, premium system is actually less current than the versions it replaced. Thanks Nissan. I'll use my up to date Garmin and ignore the expensive ornament on the fascia.

Xtrail buyers beware! (Someone else can explain how rare replacement tyres are for the new Xtrails)

Perhaps if the government forced all the mapping data companies to work together, between them they will get it right? Then we may be able to trust the additinal voice in our car!

I've never opted for the "attached sat nav" and so can't really comment, however going on reviews the Nissan Connect system is supposedly a very good one.

The problem is how do you update the sat nav and does the manufacturer provide a link on it's main web site, going on my own expierence with a tom tom, even with the latest update it can be out of date/wrong and then there's the cost, maybe the likes of Nissan could earn some extra revenue by providing frequent updates ?.

Nissan will supply you with an update DVD every 4-5yrs (yes 4-5yrs!) for £260+ which will obviously be at least three years out of date. Nissan are supplying a real no brainer, but they will not listen. Nissan CustomerServices are really poor, and the Managing Director and his trouble shooter are no better. I bought a 2011 Tekna, and didn't want another sat nav, but it came as a non-negotiable addition with the trim. It is dire. Nissan advertise it as 'always know where you are' which is a complete lie. They blame the company that supplies the maps, but they are still peddling a worthless piece of junk, on an otherwise very nice £30K car. One guy from NCS suggested that I trade in my 3 month old Tekna against a more basic model, so I no longer have the sat nav, and that isn't a joke!
