Hi
what you need to do is to start off make sure both units are powered from the same point you will see why below. Make sure you connect the Audio Interrupt out lead (pink/black) from the 300bt to the x001 INT IN pink/black wire
Go to general settings turn off the int mute setting, (you proberly have it turned off already the reason your not seeing it) try resetting it using the small button behind the face plate. This should allow you to see the int mute setting. Go to the bluetooth settings and select adaptor. Disconnect power to both units. ( you will need to re apply power to both units at the same time) after around 10mins. when you re-connect the power make sure ALL bluetooth units around the car are turned off. You should now have success in pairing the phone and having the X001 recognise the 300 bt.

You connected your blue alpine wire (power antenna) to your blue wire (amplifier remote on) on the BMW harness adapter. You need to undo this, amputate your blue alpine wire (because your E36 has no power antenna) and connect the alpine blue wire with white stripe (remote power) to your blue wire on the harness adapter.

When you switch source from the radio, alpine is shutting off your amplifier through the connected power antenna wire. Since you're not listening to the radio anymore, it sees no reason why it should give it power.

Niether .... do you know what you have in hand? Both those extras costed someone some cash ... OK here it is: the CDA-9884 has a dedicated input for ipod (a KCE-422i cable is needed and comes with the new CDA-9884 in the box) ... The HD radio unit allows you to recieve new HD radio signals (digital radio, and stations that have it in your area may also have extra music streams like HD TV does). The bt-400 is a bluetooth adapter to use bluetooth enabled devices with such as a cell phone. If your ipod has bluetooth you could used the bt adapter but I suggest the KCE-422i cable instead, and check out the HD radio too, it's pretty cool.

There is an option in the unit itself to turn off the internal amplifier. If you push the 'menu' button, then go to the setup/settings menu, and then i believe it was under the 'general settings' tab. there's a option called INT IC or something. Make sure that is turned on.

The hard drive must be formatted in FAT 16 or 32 for the Alpine to recognise its there. It came pre-formatted in NTFS.This is an easy fix once you know the problem. Just save your data/music onto another drive.Then use a program like easeus partition master (free download) to reformat the external drive in FAT32. Move your music/data back onto the drive and the Alpine will now see the drive and all your music. As a matter of interest some people say you cant format a drive bigger than 32Gb in FAT32, but I had no problem with the above method on a seagate 500Gb drive. Also apparently some head units cant deliver enough power to spin up an external usb powered drive, but again I had no problems with the above combination
