Hello All,

In the past weeks I have been upgrading my sound system in my X5.
I will post some install pictures soon.

My car used to have factory DSP, but thanks to the instructions of El_duderino I was able to convert it back to normal 4ch output.

To interface with the balanced outputs I used the Alto Mobile UI-4, which works reasonably. Not perfect because it picks up alternator whine/noise which I have not been able to solve. I will check out later if I can fix this, but for the time being I use a rather cheap LOC from caliber which actually works fine and noiseless.



For Amps I use:
-1x Alto Mobile Class D ADP 204
- 1x Alto Mobile Class D ADP 304
- 1x Helix A2 Competition for the Subs.

Both in the front and rear doors I have the Boston Competition 16,5cm woofers + tweeters. And for mids in the dash I currently use Omnes 6cm midranges.
For sub I use 2x Phase Linear Alliante 12" LTD

Finally to optimize the sound I use the Alto Mobile UCS Pro DSP signal processor which can be configured with a laptop.

I also have the Dension ICElink for my Ipod. This works fine, and shows the track titles on the NAV screen, but in the MID/Dash screen it does not show the titles (just CD 1…, etc.). I have the latest firmware (2.b2) on the ICElink. Is it possible to enable track titles in the MID display??

I am also planning to buy a DVD player. Unfortunately my car has the ‘older’ radio BM24 module, without aux-in. However I think it should be possible to connect the DVD line-out to the red, white and black wires from the ICElink and use some relays/swithches to switch between ICElink input and DVD input. Has anyone tried this yet?

Final question: is it possible to have the NAV screen (16:9) display the DVD picture and thus ‘overriding’ whatever it is displaying (Nav, radio, TV, etc.)??


Many thanks!!!
