I have an UNGO MS 8300 that I would like to sell... I have decided to buy an alpine system and the alpine alarm will interface with my head unit... Um I have not had it in the car for more than a week, everything is included including the diodes soldered in and all, proximity sensor, siren, and everything. I am asking 150.00 or a reasonable offer. It works and is perfect I just would like to buy this alpine unit. drop me an email.
