    I have exactly the same problem with my 2001 BMW 740i (E38). Blank navi screen; radio/CD player cuts out after about 2 1/2 minutes (must turn if off and back on again for it to work, but again for only 2 1/2 minutes); navi CD will not eject - VERY FRUSTRATING!

Stereo fuse keeps blowing


Check wiring for any shorts. If none found remove radio and harness and test on a seperate battery or power supply. If still blowing there is a problem with the stereo.

A good local car audio shop can help you out if you need.

NEED STEREO WIRE COLORS FOR 1988 BMW 735I


red = constant live 12v
brown = negative ground
violet = ignition live 12v
white = electric antenna (rear screen)
the speakers will be twisted pairs, i can not remember which is left and right but the grey stipe and brown strip are negative the others are positive.

If in doubt get a pro to install for you as you could cause damage if you connect wrongly.

Hello rbs845,

Most vehicle audio integrated phones use a ground on a specific wire from the receiver to activate the "mute" function. If the wire contacts other wires or shorts to ground, it can cause the receiver to signal an incoming call or mute. Without the exact make and model of the receiver, it's not possible to point you to a specific wire color to look for. I'd make sure that ALL wires that are not used are securely insulated and kept from touching other wires or metal behind the dash.

Hope this helps.
