Motorola Bluetooth Integration installed.... (kinda long and lots of pics)

[hman_a4]

I did this over Thanksgiving weekend and finally got a chance to post this. First, there are many phones and many Bluetooth kits out there. This is only one option available - I don't profess this set-up to be the best, but it fits my needs.

Phone Model: Motorola v-505
Bluetooth Kit: Motorola 98500 / S9642C

Why Bluetooth? 2 main reasons:
1) Bluetooth functionity allows the phone to integrate with the phone functionality that is already wired into Audi's without any wires. Meaning, I can now sit in my car and place calls by voice while the phone is remains in my pocket.

2) But more importantly, you are no longer tied down to the phone. One disadvantage of non-Bluetooth phone kits (such as the Nokia 8260's I had prior to this one) is that the hardware is specific to that particular phone. Therefore, I was 'stuck' with the Nokia even as phones got advanced and had more features. So now if there is a new phone that comes out in the future with features I like, if it has Bluetooth, I just have to take a minute or 2 to configure it to talk to my bluetooth kit I installed in that car and I'm in business. All the hardware I had from the Nokia kit is now useless.

Here's the kit and it's contents:


Basically, I connect the kit to the car in the same manner as when I did the Nokia 8260 integration. With an additional DB25 straight-thru cable, you plug it into the cable coming out of car in the CD-Changer area (B5 A4) and cut the cable as shown here.

I really recommend this method - as there is no soldering required with this approach. More details on that in my Nokia 8260 article

Then connect the wires from the kit as diagrammed here:
PIN on DB25#: -----> LINE:
10 -----> Orange <Stereo mute>
16 -----> Red <Unswitched> Isolate with fuse
5 -----> Green line <Ingition sense> Isolate with fuse
3 -----> Black <ground>
19 -----> Speaker + (white line)
25 -----> Speaker - (black line)
15 -----> Mike + (white line)
14 -----> Mike - (black line)
[The Yellow and Blue wires are not used]

You cut the speaker and microphone lines in the kit and connect them to the appropriate lines listed above.

I placed the Junction Box (the black box in the 1st pic) behind the dash and Control Unit on the dash console as shown here:



It's possible to place this elsewhere - by the handbrake area or to the left of the steering wheel. I considered both, but I prefered this. Somebody more creative than me will come up with something else I'm sure.

The blue button on the Control Unit is the main Bluetooth button. When the ignition gets turned on, that button flashes until a connection is made with the phone. When the connection is made, the buttons remains lit and the phone is now in Bluetooth mode. Here's a pic of the phone getting connected to the kit - again, this can happen with the phone in my pocket. This is just for demonstative purposes:


The circular button in the middle is the Mute button. When a call is established that lights up in orange. If you press it, the mic is muted and it flashes. When you want to resume, you press it again and you can speak again. The Button next to that is the Voice Recognition button. If you want to make a call, you press that button, the radio is muted and it displays "Phone" and a sexy British female voice says "Say a name" You then state a name you have programmed - "Linda" for instance. Then it says back "Calling <Linda>" - and joila the call is made. The 2 buttons on the right are volume buttons...

Here's a night time shot:


It took me about an hour to install this because it basically sat on top of my old installation. But if doing this from scratch, it should take about 3 hrs.

Other cool things/features:
-If you want privacy, you simply press the Bluetooth button until it is unlit, then you can just use the handset as normal. You can do this even when you're on the phone.

-You can program a 'keyword' to use when a call comes in. In my case I use "answer". When a call come in I say "answer" and the call is picked up.

-The kit supports 2 types of voice dialing, the phone's and the kit's own internal voice dialing. The kit's has the voice prompts and has to be programmed/trained separately.

-When the battery level on the phone is running low, the Bluetooth feature gets disabled.

-You can configure a few other optional setting to fit your preferences - ringtone, auto-answer, etc.

-The Bluetooth kit is available from the Motorola site (www.hellomoto.com) for about $210, but I got mine at www.getyourtech.com for $135.

the point of Bluetooth is that there are no wires between phone and the car.

Would you say this kit is better than just a bluetooth headset? I am starting to wonder if car kits are even necessary anymore...

but i can't answer it being that i've never used the Bluetooth headset.

for me, the 'speakerphone' nature of the carkit makes it cool - on occassions where you want a passenger to hear the conversation too. just the other night, my lady friend jotted down some info that was being given while i drove...

it comes down to a personal preference...

for me, the headset is extra effort - putting it on everytime. with the car kit, you never have to think it about it. the phone can remain clipped on my belt or in my pocket... i don't have to do anything extra.

I've seen past posts about hardwired kits that require the OEM mic to be swapped out for the one with the carkit.

i've heard and read about the incompatibility issues with the OEM mic - so i just went with the kit's. i placed it in that area - much like how i described it in my 8260 article...

The DB25 cable for everything. I actually mounted my BT Unit back in the CD Changer compartment that way I didn't have to run wires into the cabin. I then used the pin-outs on the DB25 connector for the Ethernet cable port in the console and ran the controller from there since it uses an RJ45 type connector. I haven't quite figured out where i'm going to place the controller yet.

Regarding the stock mic...I couldn't get it to work so I disconnected the stock Mic removed the internals from the black box, removed the internals from the kit mic, then spliced it into the stock mic connector. This way it is shielded the same way the Stock Mic is and it doesn't hang out anywhere.

I like where you put your controller though....

Nice Writeup!
