Question about Delphi Roady2 SA10085 XM Radio Receiver with Car Kit

1 Answer

No power in car

My unit has worked for more than a year in my car. Now it gets no power from the lighter socket. I have tried it with the AC adaptor in my home and it works fine. The lighter socket works with the lighter and with my cell phone charger. The Delphi Vehicle Power Supply looks OK. If there is a fuse, I can't find it. Do I need a new Delphi Vehicle Power Supply?

Re: No power in car

Try a tester on the car lighter power cord( usually auto parts stores countermen will do it) to make sure the cord isnt shorted. It sounds like that might be the problem. Good Luck. I found that if you constantly move the unit from car to home the jacks start coming apart internally. the solder joints break and the connection gets spotty. I am on my second Roady 2 because of this.You can get a T6 tork driver and take them apart if you feel up to it or buy another one on ebay or craigslist of they have one. Good Luck

Engine noise through sirius

First check fo good ground on lighter socket sometimes manufacture's use whats called a floating ground which is one wire connecting every socket for a ground . This creates what is called a ground loop and can create noise. Instead of rewiring try an inline noise filter. check with your local car audio store. Hope this helps. If not write back.

Tao won't start

Dear Jim,

My own Tao unit is dying as well. Servicing does not appear to be available. The only solution I have found is to buy the Delphi MyFi unit which appears to use an identical interface (see page 10: ). What a bummer!

Power but no signal

I work for sirius so I know about all of these different issues and the most common one is the connections. It is imperative that the radios be connected to power with the cig lighter adapter. This adapter had circuitry in it that lowers the cars 12 volts to 5 volts which the sirius unit ooerates on. The old units were 12 volt and could hard wired into the vehicles fuse block, but all of the new radios operate on 5 volts. If this is not the issue with either of you then you have defective units. Being that all warranty replacement are with remanufactured units, your chance of getting a problematic unit increases after the initial return of your new unit.

Sportster 4 not working...

I had the same issue. This is what Sirius calls a "Frozen Unit". There is no bypass, unfortunately, and it must be returned.


I had mine for 3 days and it froze on the Sirius Logo screen when booting up. If you bought the unit from Sirius, you must contact their E-Commerce department. If bought from a retailer, take it back to the store.


Sorry, mate.

A/C Adapter Noise and Interference

We should sue Delphi for resolution of this problem. I feel that the adapters are a fire hazzard.

Noise with casette adaptor

Well Jill the problem you are having is called inducted noise. The lighter power adapter cord is inducting electrical current to the cord used by the cassette adapter thus creating the the noise you've been hearing. Do your best to separate the two cables as much as possible. I realize that your unit may have both cords coming out of th same side, and that's fine. the longer the run of wire, the easier it is to have induction issues. If the cords do come out on the same side, run one up and the other down away from the other cord. Do not coil the lighter adapter or cord either, it increases the chance of being able to induct noise. If your unit is to close to the lighter assembly you may need to move the unit to another location in the vehicle itself to help combat the noise issue. Other options include to shield the cassette adapter wire, i use aluminum tape for heating/ac ducts. The only other option i can see is purchasing a FM modulator which will transmit the units sound wireless-ly through an FM radio channel. You will want to check and see...i do believe most XM radios have a FM modulator built in. Hope this helps, and good luck.
