My ND1 display, the one with the silver surround developed a fault. A thin blue line down the centre of the screen. Didn’t stop it working but quite annoying none the less.
I could have bought a new LCD screen from China for about £35 but instead took the chance to swap for the later display as fitted to the ND2. Black surround which will cut down on reflections in the windscreen and also the display is brighter and with more detail.
It’s a straight swap if you can find one from an ND2 but I went down a cheaper route. The parts of the display that’s needed is common to the Mazda 3 and Mazda 2 from the same era. Mine came from a Mazda 2 and I had to swap the rear cover and mounting brackets from my old screen. Not too tricky and the results are great.
So why didn’t I get an ND2 display which would have made it slightly easier? Well to find a used one in good condition on eBay from a breaker you’ll have to pay somewhere around £140. I picked this one up in like new condition for £70. Result.
