Please can anyone help. I recently purchased my dream car a Range Rover Vouge, its the 2007 model and I love it. Unfortunately I must of left something on in the car and it drained the battery. I got the car going by jumping it and now the sat nav wont work.

On starting the car and selecting the Sat Nav I am asked to agree to the distraction message, after this I am then told that the wrong CD has been entered. Its the same CD that was working before I jumped the car.

I have checked the fuses behind the glove box and I have also disconnected the battery for half an hour and re connected it to see if a hard reset would work.

Please can anyone help. I am very stuck

That sounds like the firmware in the DVD drive has corrupted. What year navigation DVD are you using? Unless you're using the latest one it makes sense to update it. The DVD contains firmware for the navigation DVD drive as well as the mapping information so updating the disc also updates the firmware the first time it's inserted.

Plenty of last year's discs on the bay or alternatively, check on fullfatrr.com where they come up for sale occasionally. Probably best avoiding main dealer for the latest disc, unless you like being fleeced of course.

BTW, if it turns out that the drive is actually goosed, these are common to Disco 3, RR Sport and L322 Rangies from about 2005 on (2006 in the case of the L322) and can be found on the bay quite regularly. Guide price is about 150 quid S/H. There is also a repair service advertising on there at about 280 quid which is steep. Not as bad as main stealer though.

Thank you. Will give that a go for sure.

The year of the DVD is the one that came with the car so its 2007. Why would it be a problem however after the jump start and working perfectly well before?

Well, jump starting a car with so many electronic sensors and ecu boxes is never a good idea if it can be avoided. Depending on the jump leads used the car will experience high current inrush when they are connected, then a quick lift to normal voltage. Fine so far.

Then you turn the key to start and unless the leads are of national grid capacity you get low voltage and high current again. If it doesn't start first turn, every time the key is released the voltage will spike up again.

It's all a bit violent and should be a last resort.
