So far the only one I can find with the stock HU is Blitzsafe Hon/M-Link1 DMX V1..... or at least Blitzsafe says that one will work....
"this adapter connects to the 14-pin CD Changer port on the back of the radio. "
I thought the cd changer was part of the HU on the Type S...
Think I'll pull the HU when I get time time and take and see if it has the open connector that they say it would plug into...
