Title: Head unit keeps resetting....
Post by: DarkAngel on 19 May 2006, 21:53

Just put in a new Alpine headunit this evening, using the ISO connectors. Was just a straight swap unclipping the old stereo from the blocks over to the new one.. But have stumbled across a small problem. Now everytime I turn off the ignition and take the key out, When I start the car again and turn the headunit on it's all been reset..ie everything right down to the stored radio stations..I can re set-up the unit, and lo and behold it'll reset again.. Now did I miss anything out when I put the new one in.. as the old unit never had the problem but I did notice it had something wired to it which I removed as it wasn't connected to any of the ISO connectors. It's driving me mad having to re-tune and set the EQ etc before i even begin to go for a drive  :sad: Any help would be appreciated, before I had to go book it in somewhere to get sorted :\  car is a Mk3 Golf btw.

i think you need to swap the red with the yellow

yup... just swap the red and yellows over. Really easy to do on an alpine as they've kindly used bullet connections!

Ah right.... So the two long leads that are seperate from the ISO blocks I just need to swap them over, red to yellow and yellow to red? And it'll be done? Or is the leads on the ISO blocks I need to change?

It should be in the ISO block, just change em around so they are yellow/red and red/yellow, then the radio will keep a permanent feed and keep its memory :cool:

i know this is an old topic but i have just fitted a sony mex-bt3600u in my mk3 and am having the same problem as the op, is it the same for any aftermarket head unit, just swapping the red and yellow from the cables coming from the head unit??? thanks  :smiley:
