Bmw 728i E38 Audio/sat Nav Problem
 

Hi, iv got a 2000 bmw 728i and the television in it works fine, except there is no audio. Tried the tape and cd player and theres still no audio. The sat nav wont load up when you click it, just says please wait for ages. When you try a few steering controls, on the speedo a display message of "INSERT CARD!" comes up. Does anyone know what this means? where do i insert this card and what is this caRD? thanks

Hi, iv got similar problem with my '99 728i. I hope to solve this problem by finding sound amplifier. there may be some sockets that came lose or something. If some1 can send me repair manual and user manual(need fuse box in English). All things are in "D"

hi again, i have solved my problem. Open trunk and in left side behind interior u will find place where all sound and navigation boxes R placed. I have fault in first left box, where were two antenna cables and white and blue sockets( like on the back of cassette player and tv- monitor).
