Ive been trying to install my alpine idatalink maestro and an aftermarket alpine backup camera into my daughters 2010 Jeep wrangler and keep getting 2 blinking red leds which means 4 pin data cable isn’t communicating with headunit or ive entered the serial number wrong when flashing. Ive tried re entering serial number a couple different ways and neither seem to work. Also ive got all connections connected to the unit. Ob2 connection is gibing me vehicle info and radio is picking up signal through speakers but its blinking red twice then seems to be shutting down. I’m stumped and would greatly appreciate any help that some of you installers could give about this. I’ve read that alpine serial numbers are 18 numbers and I’ve read they’re 9. Not sure but I’ve tried both and neither seem to work. Hoping that somebody who installs these a lot can help me figure this out. Thanks
