Alpine CDM-7856: Can't activate AUX input!

**Bogeyman** · 04-11-2005, 02:13 PM

Hi! I have Alpine CDM-7856 HU and I need to activate AUX input. I connected
KCM-122b cable and tried to activate AUX in menu (by holding F key) like
said in manual. Funny thing is that there is no AUX option! Does anybody
know how to solve the problem?

Thank you!

try to press and hold the POWER/INITILIZE button for a few seconds. Use the TRACK UP AND TRACK DOWN buttons until you see AUX IN OFF then hit your source button i believe to turn it on

I tried it but it doesn't work. Maybe it works for some other models. Thank you anyway.
I also mailed to Alpine. We will see.

i hadda 7892 where the aux stopped working all together. Alpine's tech support sucks ***.. they'll just tell ya to send it in.

also if there is a pink and black wire it is the audio inturupt wire you can hook this to a toggle switch, you can activate the versatile link by switching the interrupt wire to ground (-).

And to think, I just bought one new from circuit city for $200....you may want to check them out for a better deal (they went on clearance in january, good luck)

That actually sounds like the first 9813 ('03 model) I bought at the circuit city by my parents house. I should have known better when after I installed it, I had to eject some cd that was left in it when it got returned (I bought it as a NEW unit). I was ****ED. I don't even know what was wrong with it, but it was f'd up. I had bought one new off eBay anyway (just hadn't shown up yet), so I was just swapped them out and gave them their crappy unit back. Even best buy doesn't do that (AFAIK)!
