please help me i can't decide between getting a
pocket Pc with a navigation software, or a navigation unit for my head unit(monitor)

i like the pc for being able to change between cars, but i don't know if the nav unit is a cheaper option''
what pocket pc shall i get , and if anyone selling one

 

The pocket PC version, while good, isn't as good a quality as the in-car one, especially if you've got the tv headunit to go with it.

What TV have you got - many brands do a very good option for their TV screens. Or you could take a look at:

and the Blaupunkt DX-R52 for £499 (if your not bothered about looks)

 

Ping me if you fancy the Blaupunkt. There's a job lot of overstocks doing the rounds and £499 can be beaten which makes for a nice cheap nav.
