Our take on the Sony XA-C40

by Robert Ferency-Viars
Sony

The XA-C40 Source Selector lets you connect up to three Unilink system sources to your Sony in-dash stereo. Your add-on options include a CD changer, satellite radio, iPod® adapter, and more. This XA-C40 Source Selector comes into play when just one of those sources isn't enough for you.

If you need to connect more than three pieces of equipment, you can add up two additional XA-C40 Source Selectors for a total of up to seven pieces of Sony Unilink gear. You can only connect one satellite radio to the system. It'll work with either of Sony's XM or SIRIUS tuners, but only one of them at a time. Warranty: 1 year.

Features

Overview: The XA-C40 is used to connect multiple Sony UniLink source devices to one UniLink controlling head unit. It has a UniLink bus output and left and right RCA audio outputs which are connected to a compatible head unit. There are 3 UniLink bus inputs, each of which is paired with left and right RCA audio inputs. You may connect up to three Sony UniLink devices (changers, satellite tuners, etc.) to this adapter, or connect 2 devices and an additional XA-C40 - which in turn can have three devices connected to it for a total for 5 devices. A maximum of three XA-C40s can be linked together, which would allow you to control a total of 7 UniLink devices.

Satellite Compatibility: Only one satellite tuner can be used with the XA-C40 at a time and it should be connected to input 1. Either XM or Sirius is compatible, just not both at the same time.

Known Incompatible Sony Models: This adapter is not compatible with the following Sony CD-changers: CDX-45, CDX-51, and CDX-52. You also cannot connect the XA-C40 to the Sony MEX-BT5000 headunit and use both the XM adaptor and the 158XA110IP iPod interface. In addition, the Sony CDX-F50M Marine Receiver  is not compatible with this multi-changer adaptor.

Simple to hook up and easy to use. Head unit recognizes everything that's
connected through this unit. That may be related to the fact that it's all
Sony equipment, but I've got a cd changer, an HD radio receiver and a
satellite radio adapter all running through it without a problem.

Works great but I could use only one. These units cannot be daisy chained.

Unilink Bus not ready for prime time

Written By Gregory, SF, CA on Friday, November 02, 2007
 
The Sony Unilink system is not fully ready for prime time.

Here is my configuration:
Sony GT710 HU,
HD ST1100 Tuner,
120IP Ipod Adapter and 110IP Ipod Adapter,
SIRSNY Sat Tuner,
XAC40 Source Controller.

I wanted to have everything connected, Ipod, Sat, HD, but it will not work. The pass through bus system doesn't work well together with the Ipod adapters. The HD will work with the 120IP, but not the 110IP, the Sat will not work in combination with the ipod adapters PERIOD.
I had to buy the Source controller just to try every combination because the Sat won't work with the HD pass throughs. (getting my frustration yet?)

So here is the bottom line. You can use HD and the Sat tuners if you have the XAC40, but you cannot control an Ipod with the Sat tuner installed. You can use the ipod through the front panel Aux.

Sony needs to correct these problems and make it easy to hook up any combination.

Gotta think when you use this

Written By Sean, Tampa, Florida on Friday, June 15, 2007
Crutchfield Customer Review (What's this?)
 
First off, many kudos to the Crutchfield staff for their excellent service. After reading the reviews and garnering what meager data could be found, I installed this w/a CDX-GT400 running a 757 CD changer and the Terk XM adapter and radio. Sony even included a special note that the XM MUST be plugged into input 1. Which worked fine except for no sound; I changed the audio over to input 2 and you could hear XM over the CD source. Hmmm... Crutchfield sent me a replacement XA-C40 in record time; it also performed the same. In sheer desperation I tried every configuration I could and it ends up that everything works... with the XM on input 3 and the changer on 2.

All in all a good unit, usual Sony quality & performance; but I agree with the other reviews; the lack of documentation is deplorable. If at first it doesn't work, keep changing it around, eventually it will.

Works, with reservations

Written By Rich, New Jersey on Monday, January 29, 2007
Crutchfield Customer Review (What's this?)
 
I experienced the same problems as Bob from Atlanta with my MEX-BT5000. A call to Sony resolved the problem. The head unit requires resetting after everything is connected, with the engine OFF (not in ACC, either). Once I did that,the problems went away - data transfers nicely from my iPod, Sirius tuner works fine.
The downsides? It ticks me off to have to spend another $100 on an accessory to connect my accessories. The lack of instructions regarding this reset procedure are inexcusable. I was close to just sending everything back - I don't like spending this much and buying installation headaches as a bonus.
In the end, the product does work, and I have all my features...

Does the job

Written By Bobby, Magnolia, DE on Monday, December 18, 2006
Crutchfield Customer Review (What's this?)
 
Not much to say about this besides that it does its job. I just wanted to point out that if you are hooking up a xm tuner and a disk changer then the tuner needs to be plugged into 'Input 1'. Other than that, this unit will need to be hooked up to power and a ground. Make sure it is hooked up to a wire that gets constant power and not just when the car is turned on because I made this mistake and my headunit (which was wired correctly) would not hold the presets I had input for the XM stations. This caused a frustrating week until I pulled apart the dash and fixed it. Finally , the unit is rather large (like 1/2 the size of a VHS tape) so it was challenging to hide it in the dash board..

That Dog Won't Hunt.

Crutchfield Customer Review (What's this?)
 
I purchased the XA-C40 so that I could use the sony ipod adapter XA110IP with sony sirius SIR-SNY1. All of this was bused to a sony bluetooth MEX-BT5000. It doesn't work. I've had the car back to the installer 3 times. The installer changed radios to see if that was the problem. It wasn't. Crutchfield changed out the XA-C40 and the problem did not resolve. I can use either component (ipod or sirius) with the XA-C40 by unplugging the other device and the one plugged in will work. If i try both together the radio goes blank and has to be reset. There goes all of my saved settings. When I turn the car off the radio goes out until I reset it. I finally unplugged the ipod so that I can get the sirius to work without having to reset the radio. When my years subsription to sirius runs out I will most likely pull everything out and start over. I'm really disappointed in Sony.
