This is for a Loksound 58818 V5 Micro Next18 that is in used but excellent fully working condition. No original packaging or speaker. Bought new by me never installed and now surplus to requirements. I have tested it and it is working pefectly and I've loaded the latest firmware. There is no sound onboard other than the oroginal basic sound from the factory. Please note that Aux 5 and 6 are Logic Level 3.3v to 5v on these decoders.
