I need to know if anybody has ever successfully installed one of these in a 94 Roadmaster:



I have one shimmed and installed in one of my 1992 Caprices and was wondering if I could do the same do the 94 RM I just bought to replace the cassette deck. I know 95+ RM Cd players will not fit, also would the power antenna be an issue?

I am going to do the same thing to my wifes Roadie wagon. I took the dash apart once to do it but realised that I need to make a bracket for it to work. I figured if I took the attatchments from the original radio and mounted it to the case of the new one it should work. I also put one in my 92 Caprice with a modified bracket and it works great.

Anybody else? Still looking for a good stock CD player option for my 1994 RMSL, so if anyone knows something that will work, any help appreciated. :confused:

I took an identical cd player out of an Astro van and it was a direct bolt-in, plug & play in my 96 9c1, now it's in my 95 SS. I would have tought RM's would be the same.

'94 Roadmasters (and Caprice/Impalas too I think) have different radios and different wiring. I tried finding a '92-'94 Buick CD Player out of a Park Ave or LeSabre and all the units I could find were expensive and of questionable quality.

I was thinking about swapping in a '95-99 CD player, but I ended up picking up a used Pioneer so cheap that there was no point.

To make this work, you would have to build your own adapter harness, and you'd have to open up the dash cover a bit too, but that's more time consuming than anything else. Make sure the radio you use is a Buick unit so it has the proper dimming signal interface.

That's what I was afraid of, I've hitting ebay hard and coming up with nothing but some ancient looking ones with questionable quality. They have one that looks like it would work from a Grand National but they are top $$$. I was hoping there was a post 1995 alternative but have had no luck so far.

One thing I dislike about aftermarkets is you can't dim the lights. If I have to start rigging the wiring, I'll probably just go aftermarket.

On the GM units - I even priced a refurb from a nationally known (but also local) repairer United Radio but it was still like $200 or something insane for a GM CD player that has known problems overheating when playing for extended periods.

The aftermarket dimming thing; are you talking industry-wide or in the context of the Buick wiring system? Just wondering, because I know that both Kenwood and Pioneer make units that will dim their displays. Although.. my Pioneer that I installed in the RMW doesn't dim - maybe I need to rewire the harness so the dimming signal comes from the vehicle and not the climate control unit (which generates some sort of PWM to control the dimming of the LEDs in the Buick radio).

Just for information's sake. The 94 Caprice/Impala have the same harness as the 95/6 cars. The only exception is the lack of a VSS input wire (the harness has a socket for it, just no pin and wire). The later model Delco unit will bolt right in and hook up with no need to do anything special. Did this with my 94 (but I added the VSS input as well). Oh, so will Pontiac radios (I have a Pontiac unit in my 95 Caprice), and probably most any other GM radio. I'm not familiar with the Buick's, so can't help there.

I know the radio I pictured above will work in a 1992 Caprice because I have one in one of mine and it works great. Just don;t know about the Buick.

the wiring in a 91-94 roadmaster is the same as in a 91-96 caprice/impala, hell i think that plug design goes back to 88 actually, in 95 roadmasters get the double-din radio with the new plug. That radio in the pic will not mount properly, but it's real easy to make a bracket or shim it up to sit right, it just takes some duct tape and a little trial and error

The wiring of the '94s is NOT the same as the '95-96s. I speak from personal experience in my '95 9C1, '95 RMW, '94 RMW, and a '96 Caprice I parted out. And if you don't believe me, just go check out 9c1.com's tech section.

By all means, the signals are pretty much the same, but the connectors are different.

Looking at those connectors, you can see the later model (95) had an additional section on the connector. But the 94 connector is still plug'n'play with the 95+ radios. As I mentioned, you just need to add the VSS pin (if you want to, it isn't needed).

I don't know about the wiring connector myself, never pulled one out of a 94 or older.

But as for the size and shape of the 95-99 Chevy CD radio, if you got it to fit in the 92, then I would assume it would fit in the 94 dash also.

The reason 95 and up Roadmaster radios will not fit is because they are larger size radio. The 94 Roadmaster still use the 91-93 size radio.

The larger size is why it was an option to have both single cd and tape player both in the same radio in the newer Buicks.

The newer 95-99 Chevy Theftlock radios have a power antenna output. They seem to have pin outs for everything including steering wheel controls etc. What I don't know is if the 94 RM and the 95 Chevy radio have the same shape wire connector and even if they do, is the wires in the same positions in the connector.

If they are a different connector or pin position, you might want to go junk yarding and pick up the newer radio wire connector and splice it into your stock radio wiring leaving both new and old connectors in place so you can swap back to the original stereo if you ever sell the car or just want to move the cd to a different car.
