I'm installing a Kenwood head unit in place of my factory radio which is the Land Rover / Alpine radio with CD changer under the passenger seat. When removing the factory radio from the dashboard I see what appears to be two (2) antenna wires. One is "normal" size, and the other is smaller.

Assuming the wire with the larger connector is the antenna wire which will go to the Kenwood for AM/FM reception. What is the other smaller wire for?

 

Longwave? I honestly don't know but may be doing something similar to you so I'd love to know, too

 

In bmws that is the cell phone wire to the Trimble. Cell phones were an option in the d2. Maybe?

 

do stock dII radios have a weather band like the range rovers

 

Not sure what it is, but you dont need to do anything with it when installing an aftermarket radio... Just use the standard size one

 

It could be the antenna for the NAV system.

Did you remove them both from the head unit or was the smaller one sitting in there unused?

 

Thanks, all good thoughts. The system does not have Navigation or Short Wave however. I'm going to see if I can post a picture of the smaller connector, but it is just as you might imagine. A regular, round male plug, just smaller than the standard antenna plug.

 

Good question. The smaller connector was inserted in the Alpine head unit right alongside the bigger connector.

 

Some versions of the stereo system had separate AM and FM ariels.

take a look at the rear side windows where the antennae are located.

at the top where the headliner meets the window is a small button like connector. If you have a wire going to both then one is for AM and the other for FM.

On my 03, which had the Alpine system with no CD changer and no NAV there is only one antenna wire. there are antennae in both rear windows... Only the one on the passenger side has a wire connected to it.

I assume the antenna amplifier in the headliner is designed to pass both AM and FM in my case.

It would be interesting to see if you have two connected antennas and two RF amps.

If so you may have only one hooked up. Is either the AM or FM section weaker than should be?

 

Here are a few pictures....
