I removed the nav unit from the dash and also uncovered the radio module on the trunk under the spare tire but no wire seems to be broken or damaged, it came with this problem when I bought it and it doesn't have to do with outside forces I don't think it just does it all the time.

I'm not picky with sticking the the original part or aftermarket as long as it works and I can listen to music without it turning out every 3 minutes lol

I bought the x5 this year it has badges that say alpina on it and under the hood it says alpinweiss III 300/0 not sure it the 2 are related but it's a nice white and haven't seen one in the city like it so I'm not sure, has 22" rims on it I'm getting it done up for summer cause I'm going for the whole white and black look!

The unit in the dash is a monitor, the nav computer is in the trunk of the car, in the left side pocket, where the amp, the CD changer, the bluetooth unit, the voice control SES unit would be... the monitor has nothing to do with radio cutting in and out (unless there is a short in the harness where the monitor is, which is less likely if nobody messed with it, like poking for an AUX connector).

Radio cutting in and out is a known issue with BM53 radios which requires an actual repair to the radio (there is fellow in UK, Baris, he is worldwide known and he does excellent job repairing defective/broken BM53s and BM54, also upgrades their firmware and introduces additional inputs, like an AUX in models that did not have the AUX from the factory. Do a search for his name, he should come up on many BMW forums)

However, before deeming your radio as defective, you should do some basic troubleshooting... As a matter of fact, once you find Baris and his website, he might offer better troubleshooting technics, as he is specializing in these problems...

As far as Alpinweiss III 300 - it is a paint color code for a white color, nothing to do with Alpina...

However, Alpina badges - I am not aware of Alpina actually modifying the E53 but I could be wrong... Lets see if other folks can chime in...

How about some pictures?
