found this from another website with Alpine's tech support and it seems that I wasn't the first one to inquire on this because he handed me the answer straight away. The KCE-236B is only compatible with 2008+ models which the 9887 is not, (even though they say it is on the web site...). Anyway, the HU needs to have the AUX+ option on it and the 9887 doesn't so I have to go with the RCA adapter it seems and then a converter to a headphone jack. According to Grampi in the previous post that doesn't seem to work so good either so it seems I'll have to get an Ipod... Next time, I'll call Alpine before buying any addon product I can't find any clear info on. Thanks everybody!
