Just bought the Goodmans GNAV20 from ebuyer, i rang them, but they cant give me any info on it, ive googled it etc, but cant find anything?
Whats all this cd-rom about?
Does it use batterys or ciggy lighter'r plugger in?
Seemed to go a price to pass it up since i have 10 days to return it from when it arrives, just wanted to know a little more?
How does it update?
Thanks people ;-)
