Integrated bluetooth & MP3 playback for DSP E39s, what are the options in 2019

Read a few dozen threads on the different modules that were installed in E39s over the years... some of them not compatible with DSP. Most of these threads are now 10 years old +.

As of 2019, what reliable and affordable options do we have for a DSP E39?

My only objective is to add bluetooth and MP3 music playback capability to my 01 E39 M5 w/ DSP. And my only requirements is to have a reliable and fully integrated system which you can control from the head unit and/or steering controls. Must have high sound quality and I don't mind dumping the CD changer in the trunk.

I don't need bluetooth calls or other functions... just want to replace the CD changer with a reliable alternative for listening to music with a good sound quality.

What do you guys suggest?

Hi,

Take a look at this solution that's being developed and manufactured by a member/enthusiast

https://www.m5board.com/vbulletin/e3...-solution.html

If you *must* stay with oem audio, then this will be a great/promising solution

If this isn't/won't be for you, then looking at your list of wants/requirements, what's your definition of affordable? Reliability will be a factor, so I'd say stay away from the unbranded electronics you see on ebay/amazon offering these or similar functions.

You mention 'high quality sound' but this is going to be a moot point really if you intend to keep the OEM/DSP audio modules/speakers. Reason is the consensus for 'Sound Quality' from the OEM setup is 'mediocre' to 'ok' with many also saying it's 'poor' or 'rubbish'. There's a 'few' who say it's 'good' or great'. Look at products from GROM would be my suggestion, they do have 'phone calls' via bluetooth which you don't want, but the vast majority of E39 owners do want, so you can just not use that function if you wish as I don't think there's a specific, excellent reliability and quality product for you.

I see from your other thread you've retrofitted the OEM modules after there was one of the low quality chinese units in the car. Fair enough, but do realise/know that the older modules now are failing more often and each module has multiple points of failure and, natually, they're all relatively expensive to fix/resolve. You can get upgrades where possible, and they're relatively expensive too. The OEM DSP amplifier has had more reports over the last couple years of failing and I only know of 2 places that overhaul/repair them where possible and they're in Romania and Australia. If you don't mind keeping the OEM setup going along with those costs, no problem. However, much better value for money spent Vs modern features and functionality, reliability and a significant increase in sound quality is to go with a premium brand aftermarket shallow depth head unit. Some recent posts from members show these with an OEM looking fascia/fitting kit to give a very close to OEM look in the dash area! By upgrading the cabin speakers, adding a good 5 channel amplifier and a modest 8/10 inch subwoofer all installed well, will give you a fantastic increase in Sound Quality, performance and reliability and would be the route I'd recommend.

Cheers, Dennis!

Hey Denis, I really appreciate the detailed response.

To be more specific, if I gain bluetooth calls on my way to an integrated system, fine. Would be a nice addition, but it's not my objective.

Now when I was referring to sound quality, I meant that the addition of this "device" should not compromise or bottleneck the sound quality of the oem setup. I can live with the "bluetooth" sound quality as this isn't an audiophile system to start with... But I wouldn't want to go back to the terrible sound quality or hissing of the xtrons system I just took off from the car. The fact that it was very poorly installed didn't help as well...

Now as for budget, I'd like to keep this under 2-300$, as listening to music on the rare occasions I drive the car isn't a priority either!

Seen decent reviews of the GROM, so I'll take a closer look. One last thing, when I bought the car, it was missing the 6 CD cartridge in the changer... hence the reason why i'm after an MP3/bt alternative... Worst case, I'll just invest in a cartridge, trow in my favorite Van Halen cd in there and be done with it!

Thanks

I bought a Tunai Firefly BT module. I have it in my glovebox hardlined off the flashlight port and utilizing the OEM aux cord to the head unit. My iPhone pairs as soon as I get in the car and I can stream music with pretty solid sound quality (as you said, it is still bluetooth). It cost $35. The downfall is you can't change tracks using the steering wheel or headunit controls like the GROM. But it works well for $35 for me.

Is Dice Mediabridge no longer a viable option? I've been using for years now and the integration is pretty solid. At first - there were some bugs with the track info not coming up properly on the nav display but that's all been fixed now mostly.

I've had the GROM for a few years and I generally like it. It has some buggy elements to it but generally works well for music playback and the phone functionality is nice to have as well. For the price and ease of install I'm happy generally.

Looks like it's still around, available at ECS Tuning and other sources, under "Audiovox Mediabridge".

Mine works great. Love having the Bluetooth, USB, etc. ... just like a "new" car

I had a similar problem with ancient threads, I couldn't find where anyone was selling a GROM or Mediabridge. All the old websites and links were dead and broken. I found a used Mediabridge on Ebay, but it didn't come with all the cords and I haven't had the time to track down where I could get some. Any leads on that sort of stuff?
