I know there's been a lot of posts regarding various adapters (SNHOND3, etc.) but it seems none of them are compatible with the new 2005 TSX configuration of factory-installed XM radio. Anyone been able to overcome this problem? (By the way--my car doesn't have navigation, which may or may not make this more difficult.)

 

Thnaks for starting this and stating it well, it's been vague for too long.'

Has anyone made this work and I missed it?

As far as I can tell, the XM-equipped Accord and TSX are waiting for a firmware upgrade. The SHOND needs to react differently to another unit being turned on or off, and there may be a HW change needed as well.

Humperdood, ever get anywhere with your noise elimination?

One approach is putting a source switcher in line on the audio input harness. Anyone who's up for this, I'll help however I can - even mod the harness for you if need be...

 

I should add that I just got an e-mail from Logjam Electronics and they say they have nothing that will work (adapter-wise) with the 2005 TSX.

 

Doesn't Logjam think they have nothing for the 2004?

 

I believe 2004 is a different story because XM radio isn't installed, leaving space on the head unit for a button which I believe says CD/AUX (not sure though).

 

The 05 also has a CD/AUX button, and it supports an AUX device. However, I think (no first-hand knowledge) the XM addition in the 05 changes the switching logic of the unit, and all of the devices that work for the 04 do not know how to handle this new switching logic.
