E39 Sat Nav problem
Discussion
Hello, I've got a year 2000 X Reg E39 535i with the full comms pack. I've had it for 4 years and it's been a great car.
The 'Sat Nav' option has disappeared from the menu list and there is no power light on the Navigation CD unit in the boot, although I can still feed and eject the navigation disc. The unit takes the disc (even though power light is unlit) then I can hear some whirring for about 10 secs before it spits the disc out.
Has anyone had a similar problem? Or has the unit just had it, and should I be looking on ebay for a replacement?
Very grateful for any help

Check the fuses - there'll be a 5amp and a 15amp which run both the stereo and the Nav module in the boot.
Some of the Nav modules are also fused on the unit in the boot.
Additionally, the ignition module plays havoc with them (so I'm told) - it's a high resistance piece, and prone to failure. When it fails it plays havoc with the MF steering wheel and causes the whole sat-nav system to play silly buggers. Think it costs £26 or so from the dealers.
Alternatively, the Nav module may have failed completely?

The MK3 is very sensitive and requires a constant clean power supply, did you have all the doors open before the nav unit died? (like you were washing/polishing the car with the radio on?).
Most likely, you've ran down the battery (just enough to force the nav unit to shutdown) which in turn killed your Nav Drive.
Ejecting the disc is a classic sign of a damaged MK3.
Also, your stereo may cut out after 2-3 mins, after you turn is back on, it will do the same thing again.
If both of the above are happening to you, then you likely would need a new Nav drive, upgrade
to the MK4 if you can (approx £300 of ebay).
hope this helps.
