Hi, i bought a unit of this site www.turbopc.com.au , which has everything for my aurion. 50w x4 , pre outs, dvt tv, bluetooth, dvd, ipod connection which i have in the glove box, brilliant. just got one for the wifes corolla. everyone is well impressed when they see it and best of all i dont need the wife to navigate anymore with the built in sat nav, and lets face it we know thats worth a getting by its self. i use to buy alpine units, but now i ll just get them from these guys.
