Default I Converted an XM2Go dock to Stiletto

I converted an Altec Lansing XM2Go Speaker System to work with my Stiletto 100. Parts Express sells the speaker system for $16.88

http://www.partsexpress.com/pe/showd...number=309-304

The connector is compatible with the Stiletto, but the pins are slightly different. You only need to solder one wire to connect two of the pins for it to work with a Stiletto (and it should still work with an XM2Go).

Here's how it's done:


Remove the white sticker just above the connector to reveal two screws.



Remove these screws and pry off the gray cover on the bottom of the connector.

This will reveal the following little circuit board



Note the little spring at the bottom you will need to hook this onto the cover when putting it back on.

To make the Stiletto work you need to connect the audio ground pin that Sirius uses to the audio ground pin XM uses. They are highlighted below:



I soldered a wire in connecting these two pins:



Test it, and put everything back together.

To get the spring to hook on the gray cover I used a piece of thin wire several inches long to hook the spring and pull it up, then snapped the cover on most of the way and pulled the wire out.

Replace the screws and sticker and you are done.

This dock charges the Stiletto and plays the music through it's speakers. It also has auxiliary in and sub woofer out. It comes with an AC adapter, but can also run on 4 AAs for portability.

Parts Express has another Altec Lansing dock for XM2Go which includes an antenna, and is only $12.88. I do not have one of these, but am tempted to try converting it to a Stiletto Executive dock wannabe. Please let me know if you convert it and what is involved.

I'll try this mod. I could always use another dock! How did you know what wire was wrong? ( Trial and error?) Did you figure out the pin-outs of the connector? Thanks for posting!

Looking where the leads on the circuit board go made it clear which 3 pins XM was using for audio (since the other 13 pins are unused on this dock). Then just touching something metal to each made the left side hum, the right side hum or both hum to figure out which pin was which.

Then I found someone else here on SBS figured out the pinout for the Stiletto. Based on that I thought I would need to add three wires because they had different left and right than this dock, but while confirming the pins it worked after just connecting the audio ground pins.

I've ordered the other dock (with the antenna). Parts Express sells it through Amazon for $12.88 but the shipping is a few dollars less through Amazon (when buying just the dock). I think it was $20.87 shipped. Hopefully I can get that working too without ruining my Stiletto.

Thanks for the heads up on this deal.I ordered it yesterday morning and recieved it today.I did the mod and it "works"....but i get a terrible noise every three seconds or so...a loud buzz through the speaker about every three seconds.Any ideas?Any help would be greatly appreciated.

I do not get a periodic loud buzz with mine. Your soldering is clean, no extra pins accidentally touched? What model Stiletto do you have? Mine is a 100. Do you get the buzzing regardless of what is playing on the Stiletto? Even if nothing is playing? If the Stiletto is not connected?

this is a really cool mod! I think I could get my $20 worth out of this. Couple of questions:

Does it need the XM antenna, or is the internal stiletto antenna strong enough? Will the XM antenna work with the stiletto?

Does sirius have any solutions this cheap?

thanks for the info!

Edit: Looking into it, the antenna actually goes into the XM2GO, not the boombox. So it it looks like the ONLY antenna you can use, is the internal stiletto antenna

This dock does not support an antenna, so you can use it to listen to Sirius Internet Radio, recordings, MP3s and radio replays. Or if you have it outside (the dock can use 4 AA batteries) use the Stiletto's internal antenna for satellite reception.

The other XM2Go dock Parts Express sells does include an antenna. I've ordered it and will try modding it to work with my Stiletto. XM antennas tend to be compatible with Sirius radios.

MY soldering was clean, no extra pins touched.I have a stiletto 2.I got the "buzz" or ""click" about every 3 seconds no matter what was playing or if it was silent.....but only through the satelite dock part.If i remove from dock and plug into aux. input sound was fine. I removed my mod and unit still made noise if i docked the radio.Weird ..i should have checked the unit out of the box.I believe it was a faulty unit.
I called PartsExpress they knew who i was immediatly and asked if they could help with my recent order.I said yes unit doesnt work right.Not only did i not get a hard time from them they sent out a new unit right away no charges at all to me.They also said just to keep the old one.I was very impressed with the customer service.I will purchase from them again.
I will try to mod the new one this weekend.Wish me luck!

Default External Antenna Connector

The dock comes with this external antenna connector for the XM2Go Radio



On the XM2go radio the connector connects on top.




not from underneith as in the stiletto?

I'm just wondering if we can can splice this cable into the circuit board and be able to connect an external antenna. I also think we would need to figure out the latching resister required between the connector to tell the stiletto to use the external antenna instead of the internal one. If we can figure this out we will of accomplished a lot!

I don't have any time to do it until maybe Sunday. But if anyone has any insight into it please POST!

RFB3, I'm glad Parts Express is taking care of you and hope the new dock will take care of your issues. It is possible the Stiletto 2 is using the pins somewhat differently than the 100, though if that were the case I wouldn't expect you to get anything but static, pops, etc.

me_rubin, the dock connector does include the antenna port and there are three pins on the circuit board connected to the antenna port. The pins are currently unused. If you connect an antenna to those pins it might work. You might be able to cut that cable that comes with the dock and connect it to the circuit board and then plug an antenna into it. I think I will try converting the other dock (which includes an antenna) first.

I've given some thought to the noise problem. I think the issue is that you connected the right side channel to the proper place but you failed to disconnect the xm2go right side connector which on the stiletto could be the serial data line which would give this type of noise.

I think I might try the following:



Solder the jumper between the two pins marked in YELLOW and then cut the trace where I have marked it in RED. In this way if the source of the interference is that pin it will now be not made.

I also traced the antenna connectors tonight. You should only need the center and the shield.



The BLUE is the center and the GREEN is shield. The shield has two pins either one would work.

I'm still working on the switch for to tell the stiletto to switch from the internal antnenna to the external one. I took the headphone connector and figured out that there is 2K resistance between 2 pins.



measuring the xm2godock I get 47K between the same two. So I might have to cut that trace and then add in a 2K resister.

Meanwhile, I'll take one step at a time.

RFB3 - I suggest taking taking a sharp razerblade and cutting the trace on the circuit board where I marked the red and moving one end of you wire to the other end of the trace. I have a good feeling that the buzz will go away.

Well that's all for tonight. I was not going to do anything until this weekend but this project is getting the best of me.

Mine is converted. but External Antenna will not work - (won't switch from internal)



Notice the external antenna plug. It comes out the bottom so I can still close it up.

Inside the mods are fairly neat.




I tried a 2 K resister between the two points and verified the correct placment with my ohm meter, but still the unit would not switch from the internal antenna to the external one. But maybe someday, we can figure out what it takes to get the unit to switch. In the meantime, I'll leave the smb connector. It works well with internet, library and I took it outside to check the internal antenna. No buzzing but I did cut the trace on the circuit board. I used a single edge razer blade and cut across it a few times back and forth. I checked it with an ohm meter and verified that the connection to the old pin was now no longer connected.

I figure if I really need to connect it to an external antenna, I can just use my portable antenna cable and plug it in through the aux input in the back.

FUN Project!

myquealer Thanks for the heads up and GREAT Post!

me_rubin, glad you got it working.

Now I hope you'll try the mod for the cheaper dock that includes an external antenna... I got that dock today and have had no luck so far (with very limited fiddling). The antenna seems to work straight out of the box, though the signal isn't as strong as I'd expect. It also charges the Stiletto with no modifications.

I have not been able to get the speakers to work at all. I can't even make them buzz by touching various contacts. Perhaps the dock detects when a unit is attached and then activates the speakers and it does not detect the Stiletto (yet).

This dock also has an IR sensor, though my Stiletto remote from the car dock doesn't do anything. Anyone know if the IR signals are passed to the Stiletto to interpret, or if the dock converts them to the appropriate command? If it's the former the remote should work once the pinout is figured out and connections corrected. If it is the latter we probably won't get the remote to work.

EDIT: Sweet, this is my 500th post. I'm suddenly a Rocket Scientist.

A little progress with the new dock...

Reading the documentation it says when your XM2Go starts playing the LED on the dock will change from red to green. That LED does not change with the Stiletto, and is presumably the reason the speakers do nothing (yet).

With headphones plugged in it does make noise and even plays music (very softly when connecting the same two pins as with the other dock.

Since typing the above I have discovered I can make the light go from red to green and the speakers pop by jumping two pins on the little PCB with the LEDs and headphone jack on it.
