sounds like you got an apix 2 cid and your hu can only handle apix 1 cid.
you can try a cable like this but no way to know if it’ll work or not since this is used for apix 1 cid connecting for evo HU
if this doesn’t work, it’s cheaper to just get a new cid than a HU but if you want apple car play and the bigger screen, then keep the 8.8 cid you have now and get the evo HU and pay someone to help code in your hu/cid.
you can simply just throw the new cid in now and code in the change and see what happens before you buy anything but if you get ‘no signal’ then try this cable and hope for best.
