Adding an aftermarket XM antenna to a 200 series (1 Viewer)

[mep1811]

Thanks to @BigMF for his work on identifying where the plug was and a great video on how to take the radio out. After seeing his post , I was a mission to find an adapter so I could use a high gain XM antenna on my truck.

After much searching, I found the adapter that is needed to use an aftermarket XM antenna on the 200 Series Land Cruiser.

www.Discountcarstereo.com makes the adapter needed for this modification.

There is a slight modification required for this adapter to work and is very minor easily performed with a sharp utility knife.

Now I can use a high gain XM antenna and eliminate all the dead zones.

The customer service is outstanding, with quick answers to my e-mailed questions. Something that is hard to find with an Internet company.

Getting the radio out is not as hard as one would think. The mod to the plug is a simple cut.

I used some shrink tubing to keep the connection secure .

I've been traveling in remote Utah and have had zero drop outs with the new antenna.

FYI, if you have a newer LC the adapter is different than the one earlier in the thread:

Once you have it connected it works great. My Dissent rack was causing too much interferance with the signal. Reception still drops out in situations where the signal is blocked by tall buildings or rock faces, but tree cover, overpasses, and random "fiddliness" is no longer an issue. Also when I load up the rack with gear and cargo boxes covering the factory antenna even more it really messes with the factory antenna.

Relatively cheap mod - Antenna $35 from Amazon, adapter $25 with express shipping, fabricated bracket from on-hand aluminum angle, but you could use the one it came with. I just wanted to beef it up a little.

The coax tucks nicely in to the upper windscreen trim behind rack fairing and I tacked it in place with a bead of silicone caulk.
