Car Stereos & wiring
Back in 90's wiring a stereo was a simple process, a live, switch live, ground then speaker pairs.
In the Mk1 TT this is not the case, it used Canbus to control on and off, lights & more which makes it that little more fun.
Not to mention the amplified speakers & bose.
Double Dins
Now this is not for the faint hearted as you will have to remove the stereo surround & some of the dash to fit a new one. They are not that easy to come buy and can be quite expensive
Parts needed to install aftermarket stereo
If you are looking to fit an after market unit such as a pioneer, sony or similar you will need a few additional parts to make it all fit and work nicely.
1. Side trims to fill the gaps either side as the stock unit is a lot wider,
2. A wiring look suited to your car, i advise pulling your stock unit forward and seeing what plugs you have, this will make finding a suitable loom a lot easier and save messing around.
Like the stock stereo but want bluetooth or hands free
This is a cheap and easy option and requires little to no work, yes its not a perfect solution but takes 5 mins and costs less than a fifth of the cost of a new stereo.
A bluetooth Fm transmitter is a great choice for music playback while retaining classic stock look.
