XM hardwire install in older E46

On my 99 328i, I have installed the Delphi XM unit, now all hardwired, thanks to great info in this forum. I started out, as I lack the aux input, resorting to the tape-input (yuck!). I bought the Delphi FM modulator that is meant to install between the antenna and the back of the radio - except the modulator comes with standard car coax connections and the car does not.

If anyone is contemplating this install, I found converters through www.logjamelectronics.com

The two converters required are 40-VW12 and 40-VW20.

Apart from a tidier install, the modulator powers the XM. If the modulator is connected to a switched power supply, so is the XM. Turn your key to off powers both units down.

I didn't know if I'd enjoy XM radio, but I find that I won't go anywhere without it. BTW, I just drove this past weekend from Philly to Richmond VA and back. The trafffic info channels (Philly, Baltimore, DC) were REALLY helpful.

Cheers,

Brian

Why not use the Blitzsafe adaptor and wire it directly to the radio via the CD changer wire?
