I'm going to buy a car within the next couple of weeks so will need a Sat-Nav unit.
First time I have looked into this market so what's generally the best and what features **must** I have and which can I do without.
I'm looking to spend £100 - £200 for the unit.
I would rather buy a unit which would update with traffic conditions etc.
I'm posting in GD rather than the cars forum as I'm sure many people have units but don't visit that exact sub-forum.
