Hi,

My Mk1 has a dreadful aftermarket radio which I want to replace with the original Concert radio/CD. However, I also want to replace the CD changer with a Bluetooth receiver, to enable me to make/receive calls and play media via my phone. I have two main questions (apart from not having a clue how to start!):

Does anyone got any recommendations for a suitable Bluetooth kit?

Does anyone know of any reputable car radio specialists in the Oxfordshire / Berkshire area who know TTs like the back of their hand, that I could use if the job is too much for my limited abilities?

Many thanks!

Jools

I think the common addition is to use Connects2 using the CD multi CD player port..

Someone in here might know an official Bluetooth option... the original kit is also pretty poor isn't it?

Thanks (again!), Stuart. I'll look up the Connects option. I haven't listened to the Concert yet - I'll probably get it all connected only to find the thing's so old it's u/s (except I won't know whether it's the unit or whether I've connected it correctly!   ).

Hi Stuart,

I've looked up the Connect2 and other similar units. What I don't understand, having watched one or two YouTube vids, is what's the point of the AuxIn, especially if the mod unit and all the gubbins, are tucked away behind the head unit? Even if the unit is mounted outside the head unit, if the phone is connected via Bluetooth, again what's the point of the AuxIn? (I previously connected a Bluetooth unit to the AuxIn port on my Mk2, through which I was able to make/receive calls and play media on/through my phone without any issues. It only occurred to me later (after I sold the Mk2) that I could've probably connected my phone directly to the AuxIn.)

I think many of these BlueTooth adapters are quite old designs, and the base unit is adapted for many different cars/head units, most of which will be getting on a bit now, So originally, aux in was required for early iPods etc.

My other car has Bluetooth built in, as well as USB & Aux.
I only ever use the Bluetooth, so when I added it to the TT, I just got a little Bluetooth one without the USB / Aux / etc..

I got this one via Amazon, but is was shipped direct from them:

I've ordered a Connects2 to try to solve my phone/Bluetooth issue. Anyone got any tips, or 'watch out for...', before I start removing the fugly aftermarket (Alpine) HU and re-installing the original Concert HU? I'm very new to all this car maintenance mularky, but I'm assuming I should disconnect the car batter (-ve lead) before doing anything with the radio, yes?

Also, I've noticed that sound isn't coming through the rear speakers. Is it possible that this is simply due to a crappy installation of the Alpine HU and that it should be resolved when the original Concert HU is reinstalled?

It's probably not wired up correctly, they might have just used the front speakers and re wired it. To get rear sound through the amp an after market HU needs a special adaptor for the Bose amp socket.
Have you looked at the wiring yet as refitting an original HU could open a can of worms.

Thanks, Dave. Actually, I'm sort of encouraged, now, by the fact that there's no sound coming from the rear speakers, if you say that to get sound to the rears an aftermarket HU needs a special adaptor. That sort of suggests to me that the aftermarket HU may have simply been 'thrown in there' and just connected to what would fit, rather than doing any significant re-wiring. Of course I might be completely wrong as, no, I haven't taken a look at the wiring yet. However, to do that, I'm going to have to take the Alpine HU out...

Assuming your not Bose, check the adaptor is described as half amped, or similar, as that matches the rear amp. Front speakers driven from HU, rears from rear amp, hence "half amped, (Bose is full amped).

Thanks, Mac. I really am green regarding this sort of thing. My original Audi HU, which is what I'm planning to re-install, together with a 'Connects2' Bluetooth adaptor (which at least one other member of this forum says works fine), is a radio/CD device marked 'Concert'. The front speakers say 'Bose'.

If the speakers have Bose logos, then it's very likely yours is a Bose system. If the Audi radio is the original one for your car, (it'll show you Bose on the display, when powered up) then it should (🤞) be plug and play, as long as the PO didn't make any changes. It should be fairly obvious if the wiring/connectors have been fiddled with.
I'd get it all working, before adding the Bluetooth adapter, so you know where any niggles are.

Thanks for the information, Mac, and for the very sensible advice, which I shall follow.

Before I remove the aftermarket Alpine HU, what are others' thoughts regarding the necessity, or otherwise, of disconnecting the battery before starting? The Haynes manual states: "Switch off the ignition and all electrical consumers." What 'electrical consumers' might still be powered-on after the ignition is switched-off, and how would one switch them off?

Hi, Disconnect the battery, :rolleyes: the worst that can happen is a resync of the windows & perhaps a code for the radio.
Ensure drivers door closed when reconnecting.
