Default Alpine KCE-422i question

I just bought an Ipod and the KCE-422i cable for my Alpine 9887.
Just wanted to ask whether the Ipod charges while it is connected.
Also, does the ipod go off when the Hu is turned off????

Hey frank - I am using the same cable in my car for last year or so.

About your questions :
1. Yes. It does charge up your iPod.
2. a) If your HU is connected to the Ignition ( simpler words : HU doesnt start without the key slotted in and turned on ) , it will not do so when the ignition is off.
b) If the HU is connected directly to the battery ( i.e. it can be played without key slooted in/ turned on ).

In any case, iPod sleeps off after the designated sleep timer, once you disconnect it from th HU.

I may be wrong about the use of words here, but i hope you get the drift. Experts - please !

Nice buy, Frank

Yep, the iPod charges through that cable. I'm not 100% sure, but I think the iPod charges only when the HU is on. Will check this tomorrow.

As hkanitkar said, the iPod will display the Alpine logo on the screen for a just short while after you disconnect it.

It will be 100% stealth. Just tuck it away someplace where nobody can see it

Does it charge all versions of Ipods? In the 9887 user manual, I see the Ipod shuffle is not supported and it will charge only some generations of Ipod.

thanks for all the responses guys.

@prass: i dont think the ipod shuffle can be used to play music with the said cable, because the shuffle has a different connector altogether. hence, none of the alpines support the use of an ipod shuffle with the proprietary cables.

No, it connects to the iPod serial Tx+Rx pins. For USB, iPod uses pins 25 and 27 (Data - and +). Alpine has not brought out the lines as conventional USB (+5V, Data-, Data+, Gnd; half-duplex differential NRZI data).

The older Alpine Ai-NET connector (round or DIN socket) used to have a mux-ed single ended data bus which needed to be converted to a D+ / D- serial lines to make it work like USB. This required an external box (also for reducing 12V to 5V for charging the iPod).

The newer Alpine HUs have the electronic conversion on-board in the HU, so the connector is now a D-type (not D-sub) connector as with the KCE-422i that @frankmehta is buying. The pin-out of the connector is as below:
[Can't format the table so the data below is: KCE-422i pin, corresponding iPod dock pin(s), (description)]
1, 3 (Line-out, Right +)
2, 21 (Accessory Indicator)
3, 12 (Serial Tx)
4, 4 (Line-out, Left +)
5, 19,20 (FireWire +12VDC [in])
6, 18 (+3.3VDC [out])
7, 13 (Serial Rx)
8, 2 (Line-out, Common GND)
9, 11 (Serial GND)
10, 16 (USB GND)
Jacket, 29,30 (FireWire GND)

What matters is whether the Alpine HU can handle USB PnP and 'Disk Drive' scanning / reading. This functionality should be mentioned in the HU manual for it to read USB drives. Otherwise it will not read files from the USB drive and play them through it's DAC.

Getting them from a clearance sale in Mesa. Phoenix. But i won't vouch for their credibility till B&t gives them the rigorous inspection they deserve. More from me about them as soon as i get them in my hands. Midbasses are from USA while the tweets and xovers are being sourced locally as i speak

I still dunno which DAC will be in use when the iPod is connected to the Alpine. Will the burr brown DAC of the alpine be used, or will the DAC of the iPod be used? I really am confused about this

does that mean ALAC/FLAC's(lossless) tracks played from the iPod will sound so-so compared to an audio cd burned with the same flac tracks?
