Need help with Sat Nav systems

[ColinG]

Hi,

I've been looking into different types of Sat Nav / Sound Systems for my GTI MkV.

With so many diff types & models available. I'm interested to find out whats worthwhile.

Three units - I'm looking at are

~ RNS510

~ Auspack AVC9000-1

~ Pioneer AVH-P4050DVD

All vary in price. Is their any other Sat Nav / Sound Systems that are better.


Cheers
