I have an Erisin ES9746EN double din head unit for sale, it's been in the garage a couple of years but worked fine when I took it out of the car and I connected it to a battery today and everything booted up as I would expect it to.
It still has the protective plastic on the screen and I have a brand new external mic and GPS aerial for it.
Would prefer it to be picked up from the Basildon, Essex area or for whoever buys it to organise their own courier to collect it.
will sell for £100 (no offers)
