Odd problems after battery drain.

[X5Moe4.4]

Hey guys,
Having a couple a weird issues after my battery died and i boosted it.
So, here is the story;
I wake up for work, go to start the x5 and its dead. Pull out the booster pack and give her a boost and she starts right up.
Fast forward to end of work day. Go to start the truck and its asking me for a code on the cluster.
Now, i've had this happen before, and i would just enter 0000 on the NAV unit, and i could start it. Here is where the problem starts... my NAV screen is blank.. the MK4 dvd unit in the trunk is getting no power at all.. checked fuses, they tested fine...

Is there a way i can disable the immobilizer in INPA? i think its the EWS3 module in my car.

I got the car towed to my house and its been sitting there with the battery charger for like a week now.

2004 4.4i with navi.

Any advice?
