i have ordered the GT. it is optional extra to have sat nav on all models.Don't they produce a full catalogue?
The CR-Z catalogue on display at my Honda dealer here has 44 pages, including 20 with detailed technical explanation. The GT model is the same as the Alpha model here, but with the options (sunroof, leather seats) as standard. But I don't see any navigation system on the UK-spec car. Is this offered, too?
