Hi guys i have a Punto Grande 1.2 56 plate (no idea what "mark" it is) when i got it the led displays were all pixelated and useless... couldnt read any info...most important though i couldnt see the bluetooth code to connect my phone...i decided to change the whole instrument cluster so now i have readable display...but... the mileage is wrong and flashing constantly, and i still cant set up bluetooth... I been told of something called a "proxy alignment" would this fix these issues and is it something i can do myself? i note the car has a yellow what looks like a computer port next to steering wheel, would there be a way of connecting my laptop to it and getting some kind of software? or do you need a special computer to access this? Thanks
