2003 BMW 330xi. Bm53 replacement?

[Aregan23]

Hi my 2003 BMW 330xi is having radio issues. The problem is the bm53 in the trunk it's completely shot it's the navigation radio with The Harman kardon system. I was wondering if there's any aftermarket replacement for this? I know the bm53 is the problem because it was working fine and it would shut off sometimes when I hit a bump and I would just pull into a gas station or something and tap it a little bit and the radio would come back on. Now it's just completely gone. Any help is much appreciated thanks

Hi,

There's no aftermarket replacement that you can directly swap it with. You can either have the current one refurbished or replace with another known working BM53 unit.

You can send it to one of the few USA specialists who refurbish them

There might be more USA based specialists so have a search around.

Over here in the UK, a specialist I've met many times at events and shows etc runs Carphonics - http://www.carphonics.co.uk/ have a look here as he also has upgrade options for the unit you might find useful. If you send it in here, you might as well put those upgrades in as well!

Cheers, Dennis!
