Radio & CD Player - What would you do?

[SLEX Runner]

Dear all,

I would appreciate your expert opinions on this little but major decision to make.

I am 2 weeks old in enjoying my 95 540iT which I placed an order of from Japan about 2 months ago. Having been exposed to sushi , the car's audio set up is for the 78 to 90Mhz only on FM band. Additionally, the CD magazine (Pioneer CDXM30) was missing. Ergo: 3 problems

a. The radio is not tuned for the MiddleEast
b. The CD changer couldnt be operated
c. I dont have cassette tapes anymore

I have also noticed that the radio system of the 95 540iT sounded pale (weaker) compared to the system installed on my 91 535i

Yesterday...I had a knee jerk reaction and bidded on ebay.uk for a KEH-M9300RDS with a CDXM30 (simply because it had 2 CD magazines together with the package) and won.

I was thinking of just using the CD magazines and keeping the CDXM30 as a spare. Doing this would solve problems B&C

Would you however ever consider installing this high-end radio?

Or would you stay pure and instead consider on looking for a Pioneer-BMW head unit that will match the existing systems wiring?

Thank you all for your time!
