2001 bmw 740il when the radio is turned on all i hear is static. it does display the chanels but no reception. the cd or cassette won't work either. any ideas?

Question edited for clarity.
Question moved from MISC to BMW 740iL.

Does the new key have a transponder chip in it? Did you check? If it does, you need to reset the alarm and immobilizer, if not you need a proper key and not a Valet Key.

the Radio is Fuse 69 in the luggage compartment.

One of the problems with AM reception iam afraid but here i suspect that the aerial mounting isnt earthing properly thus causing the AM reception to be susceptable to interference

I have the same problem but after reading all kinds of post I've learned that there are a number of things that may effect the nav screen and the radio intermitten turning off after a few minutes.

1) is called the magic reset. Look up the procedure. I believe after the vehicle has been sitting and not run for a while, you need to take the negative terminal off. 20 seconds to a minute. Then re connect.

2) battery may be low. Test it or recharge it and see what happens. You may need a new battery.

3) Fuses

4) Failed Nav system or amplifier.

I'm going through mine tomorrow. See if any of the easy fixes work first.

Could have blown a fuse, or someone could have messed with the radio, or it's wiring when the battery was off, activating a Delco-Lok anti theft system.

You should always connect the CB directly to the battery as the accessory socket is full of noise. You also should choose a better antenna as these small glass mounts cannot hear signals well and magnify local noise. AM (CBs) radios naturally pick up noise as it is the nature of AM signals. Use your squelch to lesson this but too much can knock out you reception.

This is a common problem with all bmws - BMW refuses to acknowledge it but I have owned 3 and they all have this problem - The dealer blames it on the tinting (which in my car was all original from the factory) but they refuse to fix under warranty - Something about when the back window gets wet which also has the antannae in it will make almost no reception on the radio.

I have spoken to others with the exact same problem and my latest bmw 2003 is still experiencing this problem

Does your car have an automatic raising and lowering antenna? If it does check your fuses for it. If not pull your radio out of the dash, and check to make sure that the antenna wire has not become lose or unplugged from the back.

Same issue here, hardly used the unit, and have no radio reception, all else works including the CD changer
