2003 X5 SAT NAV

[Geavesy]

Hi, i'm having problems with my sat nav, all the functions work computer, tv and radio except for the nav. I can enter destination and that is where it ends. Any ideas??
Thanks

There are common faults with the nav units in BMW’s which means a diy repair or a complete new unit (£1400 from memory)

It is worthwhile checking that the disk is clean and scratch free. If this is ok try disconnecting the unit for a couple of minutes and try it again (with the ignition turned off). It is located in the near side boot compartment and will need a couple of standard radio pins to remove it.

If this does not work there are people selling the part that commonly fails on E-Bay for less than £200.

Please note that I am not a professional but these are solutions that I have found in the past.

Disconnect nav computer, leave for 10 minutes. try again

Don't know which firmware is currently installed but the other thing you could try is rebooting the whole thing following update with a V32 disc.

any help on re-boot procedure would be appreciated

I did this on a 2001 330Ci on Sunday. I thought I had 'bricked' my (mkIII) SatNav*, but what I needed to do was remove the fuses from the Radio/Navigation (check your manual) and let it sit for 15 minutes, then re-attach. I then put the ignition to position 1 and waited... and waited. I could see the satnav drive was doing something as the little LED flashed in a non-repeating way, a bit like a computer would do if accessing a hard-drive. After 30 minutes or so, the screen switched to 'update' and ten minutes later I was done...

Phew!

• the CD of software seemed to be 'stuck' in the unit and nothing I could do would remove it.

A MK IV can be had from Ebay for 300 pounds, so please don't go and pay dealer money for a new unit, if this turns out to be the problem!

(I'm not wanting to take this too far off-thread but); A caveat to this is just be aware that with many of the well-used second-hand Mark IV s the laser is quite commonly fked or on it's way out and it's a very common problem -remember this is the DVD unit and therefore the laser is more critical than with cd units (eg Mk3s) where they will keep reading long after they are past their best. (Though a new DIY laser will only set you back circa £60 - so still a very worthwhile saving over a new unit if you don't mind this)
