Coming from a brand new car with all the latest tech to the R32 was a little bit of a shock. I decided it would be wise to look at upgrading the audio systems. I missed the satellite navigation, bluetooth connectivity and so on. Also the rear speakers sounded a little rough.
The Head Unit was replaced with a Kenwood DMX-7017DABS which is a double din unit featuring DAB radio as well as Apple Car Play and Android Auto. The latter technology allows you to plug your Apple or Android smart phone in and use various features like phone calling, Spotify, google maps and much more. It's a good feature that most car manufacturers are including in many new cars now.
On to the rear speakers. The rear units were replaced as they sounded past it. I purchased the JL Audio C1-650X speakers to slot straight in. The Car is now sounding nice, inside and out!
Whilst all this has happened, at great cost the timing chain was replaced. Now the car runs smoothly and as it should!
