I just bought a 1987 740 turbo and also a Haynes manual too. I am replacing a defunkt radio in with a new cd player. The wiring diagram in the Haynes manual does not resemble what I have in the car. The original deck doesn't have a schematic of the wiring.

Since I don't get much time off to work on vehicles, I am wondering if someone can forward me the correct schematic for the radio system so I can try and install the new deck in the car. The local dealer here can't help me out because they don't seem to know much about anything it seems.

Thx

 

Do ur car has the radio equalizer or not? If have it is gonna be a pain inthe ***??? The car has an radio amplifier wich is located under steering wheel u have to take that fender locate the amplifier and look for the speakers wires...

Hey onryboy, that radio link was helpful. I just acquired grandms's 745 GLA with a stock radio. No amp. I have what I think is a din radio that is only 6 mos old. Had it installed in an Audi that got totaled. It's a Kenwood. I yanked it out before it went bye bye. Will I need the "kit" to get this new deck in the stock hole?

 

hope you can get your girl to like this car I have an 88 740 With turbo trouble and maybe head trouble I
hope not.

mine has the amp under the steering column. I took it all out. One of the previous owners must have done some mystery wiring because there's wires that are just cut off. kind of a mess.
Thx for the help. I am outa' town currently and stuck on dial up internet, so searching the net is way too slow. I should be able to handle it from here...

You can get the mount kit and wiring kit from crutchfield.com. I used it in my 740 and it worked great. Definetly worth the money.
