Can not find the radio antenna plug to attach the Sirius radio.

Under the dash seems to have a metal plate under the radio.  Is there another way to get to the back of the radio?

No sound on AM/FM but Sirius is fine

I would look at the antenna connections ... you will need to remove the unit from the dash to get to the back of the radio. [Google removal of that specific radio for your vehicle]. You may be able to get your hand up under some dash boards to reach the back of radio?

The antenna conception is typically a round coax conductor that goes to a plug into the back of the radio.

Try moving the plug around while radio is on ... if you get signal pull out connector and clean contacts with rubbing alcohol. Test again and reinstall.

Hope this helps!

Wire diagram under dash 1996 ford ranger

If the wire is firmly attached wherever it is attached, and properly insulated (i.e. "electrical tape" etc). Then that is not the problem. If the radio is turning _off_ when you hit a bump. (meaning it was "on" and then "bumps" make it go off and on again), then either the radio is loose and needs to be tightened, and/or the ground wire connected _to_ the radio's "metal" is loose; (usually a wire connected to a bolt in the rear of the radio). When I say the radio may be loose and needs to be tightened, I am _also_ saying the radio may be getting it's electrical "ground" just by being bolted onto the car (if the area where the nuts are attaching the radio to the car is made of metal and not just all plastic). // Ok... First, make sure that wire under the dash is a good solid connection and _then_ make sure it is insulated (such as with electrical tape). Then you need to find out if a "ground wire" is going to the back or sides of the metal part of the radio, or if the "ground" is being made where the radio bolts to the car (which would be the case if that area is all metal and not plastic). BTW... That wire that is connected under the dash is connected to "positive". As long as it is a good tight connection, and safely taped or otherwise protected, it is fine and can stay that way. Tighten up the radio's bolts and look to see if there is a wire going to the back metal body of the radio. Make sure it is a good connection. Finally, if the radio is tight, but there is no separate wire going to "ground," and the problem continues... Then the solution is simple. Just add a "ground wire." Run a wire from _any_ area of the dashboard that is _solid_ metal and there is a screw/bolt you can attach the wire to (such as a metal support bracket bolted to the metal dashboard), and then connect that wire to _anywhere_ on the metal of the radio where you can make a solid connection. (There is usually a bolt in the back of the radio that is meant to be used to mount a bracket to make the radio "firm." (so that it _doesn't_ "bounce" around). Anyway, you can attach the wire there if you have a nut that fits the bolt. If not, then simply loosen _any_ screw in the metal area of the radio, and slip the wire under the screw, then tighten the screw with the wire firmly under it. That will give you a "permanent ground," and the bumps won't cause you to "lose ground" anymore when the radio shakes; which it wouldn't do if there was a proper support bracket added to that bolt in the back of the radio. (I've tried to explain this as simply and clear as possible, which is why it is so long, with some "repeating myself". If you can follow this, it _will_ solve your problem). Best of luck... --Gregg

How do I remove an after stock radio from a 1996 Ford F 350 disel pick up?

Almost all aftermarket radios come out through the front. The radios come with two pieces of, best described, about 6 inch long pieces of flat metal about a half inch heigh. After removing the face plate one piece is pushed in on each side. This pushes the clip that holds the radio aside and you can pull the radio out of its housing forward and out. If you can get under the dash unhook and wiring to the radio first, and don't forget the antenna. Instead of the factory tool you may be able to use two flat dinner knives.

How do i remove the factory radio on my 1983 cadillac fleetwood

Hi there,

Locate and remove two (2) phillips screws that secure the top of the plastic panel that surrounds the radio. The plastic dash panel will pull off once the screws are removed as shown in the photo above.
The front of the radio is held in with two (2) 7mm bolt screws at the top of the radio. Remove the 2 bolt screws.
There is a hidden radio that secures the rear of the radio and is located under the radio. Pull the ashtray to its extended position. You will need to lay on your back or side and look behind the ashtray, up to the bottom of the radio.
Once the ashtray has been pull to its extended position, you should be able to locate and remove one (1) 7mm bolt screw as seen in the photo above.
Once all screws have been removed, the radio can then be removed. Pull firmly on the radio to remove it from the dash. The radio will most likely resist pulling from the dash. The antenna cable which plugs into the rear of the radio is very short and gives the radio resistance when trying to pull the radio out of the dash. Continue to pull firmly and the antenna cable will unplug itself as the radio is pulled from the dash.
Unplug (1) blue, (1) white, and (1) black wire harness connector(s) from the rear of the radio. There will also be wires extending from the rear of the radio with a plastic connector attached to the wires about 4 inches from the rear of the radio. Unplug this small connector. The radio can now be completely removed from the dash. Set it aside. You will need to remove the plastic brackets attached to the top and bottom of the GM radio. This will be shown in detail in the "Mount New Radio" section.

Hope these helps....

My 96 dodge grand caravan has no radio reception

This seems to be a common condition amongst Chrysler vehicles.If it fades in and out while driving then the problem is inside your radio.If it's just lousy all the time I would try tugging lightly on the exposed part of the antenna lead on the pass. side near the heater box. If that clears the problem then you've got to pull the face plate off the radio and possibly the whole cluster and then remove the radio just enough to remove and pinch the radio end antenna receptor.
