Hello I own a 04 530i and a 06 525i
My 06 navi keeps resetting from BMW sign and it goes blank comes on every once in a while then when I shut off the car and turn it back on it goes back to resetting I was told to check the mpm module but not sure yet...

Battery may need charging. Take a voltmeter and test across the terminals; if it's between 12.4 to 12.6, then battery is ok. Otherwise, recharge it fully on a trickle charger.
