bmw x5 e53

Hi, help needed.

I have a x5 e53, 2005, MK1V sat nav.

I foolishly tried to update my Satnav, downloaded link from internet, which was supposed to be an upgrade. However it appears to have downgraded my system, lost navigation but still have phone, TV, Computer but no satnav. There is no display on top right corner that tells me what version I have.

Is there a way to restore previous version.

Hi Brian...welcome to the Forum!

That's really unfortunate, seen that happen before.

I have moved this post to the relevant forum so hopefully someone who has the knowledge may be able to help you.

Let us know how you get on

Sorry to be the bearer of bad news but the MK4 units are easily damaged they are known for not liking non original software.

What colour screen do you have? If it is blue I fear your nav is not functioning at all and you are running on the video channel of the TV unit.

Simple things first is the red power light on on the Nav unit in the boot? Check the fuses in the cubby on the other side? If you have power to the unit eject the map disc and if you have one put your software CD in to see if it will re-boot. There may be a member near you who has one you can borrow, I have one somewhere if you get stuck.

If your Nav computer is bricked replacement/repair is silly money for such an old system you may find a Dynavin, Xtrons or Eonon unit worth considering as selling the BMW parts will cover most of the cost.

Thanks for you post. Luckily I was able to purchase of the internet a sat nav MK 1V OS upgrade, which booted my system back to life, also upgrade to speed camera. Only cost £25 and not the mega bucks BMW would charge
