I have done a search but can't really find any reviews of the CD500 with sat Nav, so please forgive me if this is covered elsewhere.
I am looking at purchasing a new Astra SRi (J) to replace my H SRi. I'm trying to work out if it is worth getting the inbuilt satnav - is it any good compared to say a TomTom?
Vauxhall don't seem to provide much information on it - although I read somewhere that you have to use a SatNav CD - surely this isn't needed all the time?
Thanks in advance for any help.
