My Alpine iDA-X001 radio is not powering up. I checked the power to the unit. At the power pin on the 16 pin adapter I am getting 14 volts DC. Once the adapter is plugged into the unit it drops to 3-4 volts DC. I tried running it straight off of the battery, and through a switch that I have installed. Neither option allowed the system to power up.

On the rear where the power adapter plugs in, it should show in input voltage and polarity. Check the power supply output voltage with a volt meter. Generally, it is the sum total of all the batteries, so it if takes 4xAA @1.5 volt batteries the voltage would be 6 volts DC. It sounds like it is faulty.

Check your power adapter. This unit REQUIRES a 9 volt AC adapter, NOT a DC one... It MAY appear to operate on DC BUT it can't generate the +/- voltages internally for sound generation with a DC adapter. This is a common problem as people try to run these on a DC adapter.

Check with Alpine for and update for you radio

tonite while driving on a bumpy road i had the dc error right after a big bump.

according to user manual,

one of your speakers connector got lose and is touching the metal body of the car giving a shortcut

-> check your speakers wiring

Most newer car receivers have a feature named something like "level balancing" in which you can adjust the relative loudness of each input (Tuner, CD, AUX, IPOD). Check you owner's manual for a similar function.

Also, are you or can you turn the level of the ipod itself up a bit?

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.

I believed so that something is draining power in your circuit. I suggest that you must activate the SIrius now and check together with the Alpine if it help fix the problem. It is maybe it turns out to be that the Sirius resist the flow of power when it is not activated.

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.

Most devices are Negative to Earth, Chassis and Positive to the Center Pin on the "Adapter". So probably any 12 - 14 Volt say 4Amp well regulated, or Switch Mode power Supply probably would power your unit.. If you don't know the exact voltage Start at about 6 Volts and work up until it works correctly.. I often use a switchable power Supply to find the right voltage and then get a fixed supply to suit.
