This kits features are fantastic and it integrates as advertised with the factory fitted equipment on the steering wheel, and as such was all I hoped for. There was also an added bonus as the parking sensors which just were sounders previously now are represented on the GID display as a pictorial image of the car and the obstacle.
The one fly in the ointment was the inability to accessibility my phone address (Samsung S3), which should have been possible using the bluetooth kit. Following interactions with the Manufacturer and Darren at Car AudioStuff, I got the software for the Kit firmware upgraded to version 4.00.00 and everything works a treat. So many thanks Darren

Fitted myself to my Insignia (CD400). Mic next to interior light. All works as expected with steering wheel controls, phonebook synced with my Nokia Windows phone no probs. Great product, sounds good even at Motorway speeds, uses phone own voice recognition. Unit turned up with next day delivery. You tube video a great help also.

The unit took about 90 minuets to fit. I started by fitting the mic next to the interior light then I tucked the cable into the roof lining then behind the passenger A frame trim and above the glove box across to the centre console, I now think it would have been easier using the drivers A frame as the glove box is a pain to remove. Fitting the unit to the radio was exactly as shown on the video.
The unit works much better than my previous blue tooth which was factory fitted into a Honda Civic.

bought this for my Astra J CD400
Its soooo easy to fit, works great - seamlessly with the factory CD400, steering controls and display!
Perfect great price and it was delivered next day special delivery!
I think if anything its added value to my car should I choose to sell it!
Great product with great service to match!

Great kit and great service. Darren even replied to an email on a Sunday when I made a mistake in fitting it. Easily sorted out and it lives up to all expectations, seamless integrated into the car. Very pleased.
