My plug on antenna came off I plugged it in and it won't work now

an antenna has coaxial connection to go to your tv from the antenna... it looks like a barrel. If it is a powered antenna it will also have a cord to be connected to power in some way (usb, ac wall plug etc) that needs to be plugged in often as most those antennas do not pick up anything until you plug them in but that depends on location and a bunch of other stuff. good luck

Check used on the rear of the radio or plug in the antenna cause I might have come unplugged

What is the make and model?

Radio shach has a solderless antenna plug(but it is a generic type).You will probably have to get this plug and a GM adapter.(GM is the ONLY AUTO MANUFACTURER that doesn't use an antenna plug like the rest.

Modern automotive electronics are keyed to the VIN through the ECU to prevent theft, you must have the radio ID #, and key it into the radio with the number pads on the radio, only the dealership can retrieve the correct code for your vehicle. Probably not what you wanted to hear.

You will need to remove your stereo from the dash of your vehicle and on the back of the receiver their will be a thick black wire that plugs into the back of the radio with what looks like a headphone jack on the end of it. If its not plugged it, obviously its not hooked up.

If you can obtain an external antenna from another IQ3600 user it
will plug into the connecter on the top of the unit and bypass the fold out antenna. I had to buy one because the windshield in my Pont Montanna would block the satalite signals. When I plug in the external antenna I do not have to fold out the antenna on the unit.
That will check to see if the unit is recieving and /or if the fold out
wire is broken. The external antenna is not Garmin specific but the
plug on the end is so another gps antenna with the same end plug works.

I have a unit like that. The antenna appears to be dead. It just searches forever and never finds anything. I use an external antenna that I got from eBay (brand is Gilsson) and it works fine. You just plug it in the external jack (after removing the little rubber plug) and it works even better than the built-in antenna.

There are several ways to tackle this problem, most of which would involve getting to the back of the radio, but before you do, make sure you have an "antenna extension cable". Then plug in the 'extension cable to the radio/sirius unit' leaving the other end to 'hang out' where you can then get access to the 'extension' cable. Then you can plug in the existing antenna when you're not using the camper or plug in new antenna that gets clear view of the satellite. Depending on your location and general direction of travel you may be able to use a 'home unit ' antenna on your dash as I do and it works very well. In my truck I often use a home antenna also, although I also have the large unit that bolts to the (tractor) truck mirror assembly.

The other solution is to find a CB repair place (often at truck stops) that is familiar with repairing, satelite antenna wire and pucks. Have them split the wire and place a male and female plug to accomodate the extisting antenna and the new antenna. This service will cost you about $30-50.00 They should find the parts needed at a satellite radio store that sells marine/business/home antennae systems. The parts are not all that common - or the CB fellow may connect male/female connectors that are unique to your truck situation - then any connectors will work but only on that truck of yours. -- Frank

Sounds like ext antennae is sick. Mine works 100% just by plugging into 3600
