Hi after three days my battery is flat on 2003 vogue replaced battery still the same car goes to sleep after twenty mins but I've noticed sat nav light on in boot is this correct any other ideas was going to change final stage resister but not sure as car sleeps ok and fan works fine any ides welcome

Sat nav light staying on ( permanently?) is not correct. I presume you can see this from outside the car when it's locked.
You could try un-plugging the satnav unit and see if it has any affect on the battery.

Yes I pulled the cover back in the boot and when the car sleeps light is still on do you mean disconnect it at the boot end as I tried the fuse but then list the radio lol

Yes, just disconnect it at the unit itself in the rear compartment. I "think" the radio should still operate as normal.

Ok will try that does unit just slide forward out of holder

It just slides forward in the bracket, there may be a lock nut on the bracket but I can't remember at the moment.
Nothing complicated about it it's self explanatory when you look at it.

Thank you I will try this Tommorow fingers crossed

Hi sat in car for 15 mins then it went to sleep but sat nav was still drawing 0.44 amps disconnected this and it went to zero is this enough to drain battery in three days it's not totally flat but not enougth to start car

At a constant drain of about 5W over 3 days it would certainly knock a hole in your battery's ability to start the car.
Faulty satnav is a common cause of battery drain.
Is it possible for you to leave the satnav disconnected for the rest of the week to see what happens?

Yes that's what I plan on trying thanks for your help the other strange thing was when car went to sleep I was still in it but alarm never went off .?
