I think that that the street name and house number system is far superior
to the postcode sustem !

However, ALL the Nissan satnavs work from a DVD that is several years out
of date !!!   That is, they do not have some roads that were completed 5
or 6 years ago !!!   I have complained to Nissan, but just got a massive
shrug of the shoulders.

The traffic system is fantastic - no other word for it.   On Friday,
warned me of a accident on the M62 and told me thew road was closed.   It
then re-routed me around the trouble spot.

Accuracy is very good - although the voice will occasionally give a wrong
direction around a roundabout- always glance down at the map.

I've only had a signal sttength problem once - in a narrow street in
Leeds with very high buildings - it lost the signal and caused me to go
down a buses only street - cost me £60.00 !

It's major drawback is that it cannot be updated unless they issue a new
DVD at about £120.   It's major plus point is its database which has
thousands of hotels, filling stations, restaurants, etc.
