Bought one of these a few weeks ago and then had to send it back to Sony for repairs - see this thread click here The sole reason I bought it was that it was the best buy in the Sept 2006 edition of PC Advisor's review of Sat Navs. I have now got it back from Sony and it is no better - basically it seems to lose signal so it never catches up with real time, so as a navigation aid it is utterly useless. I will of course be sending it back to Sony again, but does anyone have first hand experience of this model? I came across another review on the net from someone else experiencing the same problems - have I been unlucky or have I bought a duff model?
I don`t know anything about this Sony SatNav, but the loss of signal might be due to various factors, possibly you have an athermic windscreen fitted to your car. If so, that would certainly reduce the GPS signal. Check with an authorised dealer of you vehicle. You may need an additional antenna, if one can be fitted to your Sony model.
Other factors include the area in which you are driving. It is well known that high buildings, and even a lot of trees can screen the signal. Does this problem occur when you are driving in the open country?.
I see that from the Sony site that the spec: of their next model, NV-U70T, is similar to your model, (except it has full European mapping).
It states that the NV-U70T does not have a socket for an external antenna; then probably yours does`nt either. If the athermic windscreen is your problem, then it appears you are are stuck. You would need to check.
Many thanks for your helpful posts, the car in question (my wife's) is a Peugeot 206 which is one of those listed as possibly having an athermic windscreen. However, the problem is so random that I suspect an intermittent fault on the Sat Nav - drive 2 miles to the shops it works perfectly, drive back 10 minutes later no signal at all! This model does have an external antenna socket, I know because I've already managed to buy an antenna with the wrong plug on it! Anyway, have sent it back to Sony today, will update when it's returned.
