True? P.I.E. BMW/PC-PIOX Interface works only Vehicles without "DSP"

[gamini]

Hi!

I want to remove the XM commander from the existing ashtray installation to a trunk installation. An ebay listing has this bundle:

Pioneer GEX-P920XM tuner
12" IP-BUS Cable
P.I.E. BMW/PC-PIOX Interface
Antenna.

However, the http://www.pie.net/index-2.cfm

the P.I.E. BMW/PC-PIOX Interface works only Vehicles without "DSP" only.

My BMW has the DSP

What do the gurus on this forum think...would the non DSP interface work on my DSP radio?

Thanks.
