Yes there is a factory amp for non DSP system too. Like for DSP system the non DSP amp is normally located in the trunk on the left side under or near the CD changer. An easy way to know if you have DSP or not is to check if you have a sub woofer (with 2 x 6" sub speakers) on the right side of your trunk. You need to open the right cover to see the subwoofer. If there is no Sub then you have the non DSP.

Excellent information, thanks!! I was pretty sure on the whole not having DSP. I'll check my amp connections this evening. The stereo is driving me nuts!!

Had to bump this post to see if anyone knows the TSB referenced by the original poster? I'm going to the dealer on Friday and want to have some facts.

I think i have the same problem... My English is to bad.
When i start the car for a drive my sounds goes away after 1-2 min. No radio sound, no cd sound and no gps sound. But sometimes after 10-30 min when i press the on switch it work again until i stopp the car. When i shall drive again it´s the same problem.


Edit: I have a x5 2001 3.0.

i also have the same problem. no sound (non-dsp) 2001 x5 4.4

Anyone get to the bottom of this problem yet .

A cure ????

Been dealing with the problem since I bought my 05 X5 in Jan 09. Dealer is perplexed - changed out radio and antenna and still having a problem...I need help as well!!

stereo problems resolved
 

All of my stereo problems (slow changing stations, random cutting out, loud squelching sounds) were resolved when the dealer finally applied a software update for the radio problems. It took me about 6 different visits to get a tech that would actually listen to me and what I was describing and then realized there was a software update to fix the slow station changing issues (which also cleared up all my other problems).

Wow - finally someone with some helpful advice - I'll pass this along to my serv. advisor - he's usually pretty open to suggestions! thanks so much!!!

its not the tv/monitor head unit at fault. I bought another tv/monitor head unit same problem. Im pretty sure its the Amp itself thats causing the problems.
"Located at spare wheel area"

First im Gona whip it out and have a look (eg clean connectors and pop it back.
i will post my result.

Bump! Also is there anyway to bypass the amp?
