Splice two cables together to get functionality?

[pur3h8r3d]

Hello I recently bought an Ai-net iPod cable for my older Alpine head unit in my car, because I'm absolutely tired of FM transmitters. This new cable works to play music from my iPhone 4 and sounds great. Problem is the charging is not supported since it used the old circuitry from previous iPods/iPhones. I've seen the circuitry converters, but I'd rather not spend the extra money on one, if I dont have to.

My question is if I have an extra charge/sync cable, and I splice the dock connector from the extra cable in place of the old connecter on the audio cable will it work? I have knowledge of splicing wires together so thats not the issue, but I was comparing the two dock connectors together and I see that the number of pins in each one is different. The audio cable seems to have a pin connection at every spot, while the extra charge/sync cable I have only seems to have about six. I checked my old FM transmitter as well and it seems to have pins at every spot. I would just take that connection, but its not a cable. It's just a block that plugs into the ipod/iphone.

Does anyone know if this splice will work or not? Or maybe just some other knowledge to contribute to the situation? Any help would be great. Thanks.

As long as your isolating the head unit so there is no feedback from the incoming power supply then all will be good! Remember to keep the cable as short as possible.

I used to do some DIY custom LODs.....

Once you hook up power you'll most likely start getting the 'This accessory is not supported....' message.

Google 'iPhone LOD'.

HTH.

Do you know where I can get a dock connector with line out and power that I could splice together with my Alpine Ai-net cable?

Amazon - Black USB 3.5mm JACK Car AUX Audio/Charger/sync Connector for iPod, iPhone 2G/3G/3GS/4G

Or

Kensington LiquidAUX Auxiliary Car Kit with Remote for iPod; iPhone 1G, 3G

I would suggest the latter, and then splice the audio out of the LiquidAUX into the AI NET cable to get the audio into the head unit. It doesn't look like this cable is doing any 'controlling' so you'll still control the music/movie play on your iPhone.

It bears repeating.....if you don't use a 'Made for iPod/Works w/iPhone' authorized accessory, there is a very high chance you will continually get the 'Accessory not supported' message if you just start connecting things up to the LOD (btdt).

The LOD of the iPhones/iPods is no longer just passive signal inputs. The LOD expects active circuitry on the accessory side (which the Kensington has).

I use the Kensington LiquidAUX for my iPhone(s) (and previous iPods) into a JVC head unit...but the JVC has a straight 'Line In', I just made a RCA male to female 3.5mm adapter cable.....

HTH.
