I installed a new car stereo yesterday, and after a bit of tweaking (apparently ISO connections are not quite standard) fired it up and made a phone call on it.
That's not quite as barking mad as it sounds, as the stereo also has bluetooth connectivity, allowing me to play music from my phone through the car stereo, and also to make hands free phone calls. The unit has been obsolete since 2007, but the technology still works, and as it's built to a standard, this probably won't change for a wee while yet.
As I said earlier, however, the ISO standard hasn't quite been implemented on the stereo. There are 2 +ve power supplies - one permanent for the clock and storing settings, the other is switched from the ignition, and is used to power the stereo. For the last few Sony stereos I've fitted I've had to swap these round on the harness. There are the only 2 wires with Bullet connectors, so simply swapping them round works a treat. Testing them was another matter, however. Peugeot in their wisdom allow the stereo to stay active for about 5 minutes after the ignition is switched off. This means that you set everythin up, switch the ignition off and the stereo stays active. A few minutes later it switches off and goes silent - at this point you've lost your settings.
When the wiring is correct, the stereo switches off after a few minutes and then beeps to get you to take the face off. Your settings are safe.
All the same, I'm happy with it. It sounds good and the handsfree works, and you can use the remote control for the stereo to work the treack navigation on the MP3 player on my phone.
That's integrated technology!
