Alpine most unhelpful

The ISO plugs are an industry standard layout for car audio connections, one plug has the eight connector for the four speaker circuits, the other has eight connections but the ISO standard only specifies five of them, (with the ignition live and battery live sometimes transposed). The Symphony uses all eight

The three 'spare' connectors are used by the Symphony for the steering controls (Blue/Purple and Blue/Orange cables) and telephone mute (Red/Green cable). Later 75's and ZT's use separate connectors for them. (as do some other manufactures.

So if you are replacing a Symphony, make sure you get a lead that has the steering controls through the ISO plug. You will also need a Kenwood adapter.

I follow that all, thanks

Can you say why a Kenwood adaptor is needed though please?

Here's a thread at mg-rover.org where you have the ISO pinouts of the Symphony. Could be used as a starting point to build your own adapter cable:

Edit by GG (You can search for the thread on .org "Symphony HU on ebay.") If you really must

The car lead is model specific and the radio lead that connects to it is model specific, so it saves making leads for all the possible permutations of car / head unit.

The 75/ZT Symphony type adapter lead has ISO plug on one end and an ISO socket on the other, it goes in line between the loom and the head unit. (All adapter leads are like that, they have different plugs and sockets for different makes etc.) It has a connector in it that the head unit adapter plugs into which is specific to the make of head unit - you will need a Kenwood one.

I thought raistlin has got an Alpine headunit

[Raistlin]

To be frank, RayKay

That was my concern as well.

Is the Kenwood one to be used in lieu of the Alpine one please?

Sorry, thinking of another post, of course an Alpine one...............a

Thanks Ray

I was a bit confused

OK - update

Alpine do NOT, in fact, make a lead for the Rover 75 with ISO connections

Autoleads lead connects OK but doesn't function properly (ie, try to adjust volume up asnd the radio station changes, etc.)

In Car Tek - say they haven't an appropriate lead

So it seems I am now well and truly up a creek.

The only though I have had is to get an ISO to BMW converter (ie as if you were changing FROM a Symphony TO a Harmony), if, indeed there is such a beast, and then buy the Alpine BMW lead and see if it works.

Can any of the ICE guru types give me a clue as ot if this idea will work please?

OR, any other ideas?

Thanks
