I came across a device call the RediRad. Its a small box that has two leads that splice into your antenna connection on the radio and the antenna itself. With this box and a simple hookup it lets you enjoy your favorite music from your iPod, MP3, CD deck using your vehicle’s existing stereo system without broadcast interference.
I believe that the principle is the same as the forum member who recently added the 1/4" jack to his radio but this device doesn't need the radio to be disassembled. Anyone try the RediRad?

There is a unit that operates in the FM band as well.

The one below works with anything that has a headphone jack output. I didn't realize that the unit that Dennis mentioned has an FM modulator built in. That is the reason for the power connectors. Here is an alternative that is a little less pricey:

It's just an in-line FM modulator... I had one in the early 90s. I don't see anything new here and it's waaaay too expensive.

I believe the ones in the 80's and 90's worked by transmitting a wireless signal that was picked up by the antenna. You also had to tune the radio to an empty channel frequency which is close to impossible in congested metro areas and suburbs. Those units were noisy and did not work well. The current unit should work well but I agree it is pricy. The ebay ones are less expensive but I believe are for AM band radios only.

Actually I think it is the other way round....the one on the video was for AM insertion (and the EBay one and all the rest are FM)...and is being promoted to classic car crowd based on the fact that many classic cars only have(had) AM radio. I don't believe I have ever seen an AM modulator before ...that could also explain why the price is so high...because it is such a niche item.

I like the idea of having a hard-wired direct link rather than a wireless modulator. However, I'm not too crazy about having to pull the radio back out to get to the antenna cable to hook up the new unit. Is there a way to get behind the radio to unplug the antenna cable?

This is the same thing, only wired. You still have to tune to a specific channel, but it sounds like it cuts off the antenna when turned on, so that might help with tuning.

How does the RediRad™ work?

The RediRad operates like an A/B switch: In default mode, the radio receives over-the-air signals that pass straight through the RediRad. In RediRad mode, music signals from your portable music player enter the RediRad via the audio input cable (that plugs into the portable’s headphone jack) and get converted into a radio-frequency signal that the radio treats like regular broadcast. Turn on the radio, tune it to the proper frequency and ENJOY! The RediRad returns to normal broadcast-receive mode within about 45 seconds of turning off the portable music player.



It's a neat idea, but on the older AM models, you're still only listening to mono and whatever quality the OEM speakers and radio were.
Personally, for an old car like that, I'd probably prefer a hidden system with a remote that bypassed the OEM radio completely, especially in an old classic with one speaker in the dash. I can see where it would definitely have it's uses, though.

Not really (at least not that I know of). That being said ....GM radios are some of the easiest to remove...just remove faceplate...and mounting screws underneath....pull it out far enough to pull the antenna and replace it wth adaptor...shove it back in and button it back up. Just a few minutes I suspect

Thank you for posting this, I might just get this for my Fiero! I don't like tape deck adapters, they never sound right, and finding an empty AM station isn't difficult. Also I like how small the unit is, should be easy to install in less than an hour!.

Ok after reading more into the product I'm definitely getting one but I'm getting the FM one, its a great idea, and I like how you don't have to fight other broadcast coming in. I like the stock stereo in my 85 Fiero so this will be a welcome addition!

No I had a hard-wired one in my 92 Geo Storm... I had a CD player that I installed and it played through the antenna wire of the cassette/radio. The advantage of hard-wired is that it increases your signal to noise ratio and gives you a better chance of finding a clear channel, but it's not magic. It's still a modulator and it's still going to sound worse than any real connection.

An AM modulator is just ridiculous. You would be better off with a tin can and a string with the sound quality you are going to get from that.
