The last photo is on a sunny day (I changed my silver surround to black, not sure if I like it yet) so yes the sun does affect view when really bright. Factory fit DAB and Blue Tooth are completely unaffected.
I do know the earlier versions of the CV unit had problems but the unit I have is the latest version and is brilliant.
One thing I will say though...if you want to stream BT from your phone etc. you will have to turn the factory BT off and use theirs. Factory BT does not allow streaming where as the CV BT does. This doesn't bother me as I decided stick with the factory BT and leave my phone plugged in.
You have an additional USB multi port in the glove box and I leave my phone plugged into it so I can...play all my music via the CV iPod link, listen to factory USB, DAB, micro SD stored music, CD, answer the phone via factory BT and use Sat Nav all very easily.
Well worth the money in my opinion.
Look at the reviews online and speak to CV before buying anything.

I'm that impressed with this unit, I've had the CD500 and Navi600 in my last two Astra J's, that I share my findings. The CD400 / CD400+ are both old tech and this unit looks factory. Some other units look cheap, I'm a believer in that you get what you pay for!!
I had this unit installed by CV and they know their stuff.
Hope this help?
