[Biturbos4] Radar Detectors

[Nicholas Mistry]

I know this subject has been covered before, but i am wondering if any 
opinions have changed as newer versions of detectors have come out.   
The reason i am asking is b/c my father has decided to install a radar 
detector in his 2005 A8L, and wants to go with a builtin model.   All my 
experience has been w/ dash mounts and i own a Valentine V1.  

I am aware that there is a builtin kit for the V1 that another vendor 
supplies.  2x V1, enclosures, mounting brackets, remote displays, 
etc..    But im not sure that is the way to go. 

What is the best built in radar detector?   Does it compare to the V1 or 
equivalent?

Any thoughts or opinions would be greatly appreciated.

Thanks..
