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.
