2006 Avalon XM - VAIS Tech vs OEM

[walkerb]

Is there any advantage to installing the VAIS tech SLX & XMD1000 in my new Avalon as opposed to the OEM unit. Cost @ Toyota Parts and Accessories for OEM is $255 - Group buy @ VAIS Tech $210 + $15for XMD1000( ebay). Vais Tech offers aux port (for MP3, etc).
Would appreciate any comments as to quality, ease of use , installation, etc. of either system. Would also appreciate info/ instructions/link on OEM XM installation.

I actually opted for the VAIStech SLX (xm radio) group by @ $210. Main reason was the additional aux to hook up an ipod mp3 or sirius. Eagerly awaiting so I can install this weekend
