When i posted the message below I forgot about the DSP system. I was thinking about the "normal" E39 system. A mental lapse which was probably the result of posting at 2AM after being on my feet all day in our booth here at the Consumer Electronics show in Las Vegas. Sorry.
THe DSP equipped premium system is in fact a bit more difficult to deal with but still possible. Unfortunately, my Data is back in the office so I can't give too many details right now until I get back next week. I'll be back next Wednesday and will try to post more info then when I can look it up.
And, sorry, I dont really know too much about an in-dash CD solution. I hav heard that there is one available in Europe, but the European FM and AM broadcast stab=ndards are different s it may require some modification to use the radio portion.

Best regards,
Bob Hazelwood

: You have been misinformed about the difficulty of upgrading an E39. You do NOT have to upgrade the audio after the factory amp. THis is costly, complcated, and basically just asking for trouble. It will not work. The best place to pick up the signal is BEFORE the BMW amplifier, where it is a standard 4-channel common ground signal. Simply plug this into any aftermarket amp which can handle a 4V signal. No problem, No noise. You can even use ALL of the already installed BMW wiring for signal to the new amp and from the new amp and the speakers. If the installer knows what he is doing, the E39 actually is one of the most simple vehicles to upgrade on the market. If a dealer tries to tell you differently, don't let them get anywhere near your car. They don't know what they are doing.

: : Ok, so even with the premium audio I STILL didn't like the way the stereo in the 540i sounds. Sad that BMW gets EVERYTHING else right and then puts in a stereo that is blown away by what's in a Caddy Seville.

: : In any case, I took the plunge and upgraded the stereo. What an ordeal! You must hook the sundry equipement AFTER the BMW amplifier... Mind you this entails 12 channels of amplification (separate channel for each speaker driver). But it's still not right, the noise levels are too high! Does anyone know of a way to put an aftermarket radio in an E39 without completely trashing the dash and losing telephone functions? I remember Sony doing a concept car using an E39 but can't find the article ANYWHERE!
