Default Alpine Adapter - For Both XM & Sirius

I currently have XM in my '02 GMC Sierra pick-up truck using an Alpine head unit. I absolutely love it & thought I would double my pleasure by also getting Sirius installed in the truck as well.

Recently I read that Alpine is coming out with an adapter that will allow you to get Sirius too sometime in the fall.

I already have the Audiovox PnP2 for Sirius & wanted to install it in my truck, while still keeping XM & the Alpine XM head unit. I went to the car stereo place & talked to the sales manager about the best way to get them both. He was familiar with the Alpine adapter but said he couldn't see how that adapter would give you a better sound than what you would get by using the FM modulator. He said, whether you use the adapter or not, it would still pretty much sound the same & would never sound as good as XM because the head unit is XM. In other words whether I would use this Alpine adapter (that's coming out) or just use the PnP2 with the car kit that's available now - either way the sound would be about the same.

He said that by using the FM modulator you can only get as good a sound as FM can produce which is certainly less than XM. He doesn't think the new Alpine adapter will be able to do much better than the FM modulator.

Any of you techies care to back this up or dispute this? Should I wait until the adapter comes out to get the Sirius unit installed or do you think the sales manager is right in that the Sirius sound wouldn't be much different whether I use the current car kit or wait for the adapter to come out.

The sales manager also recommended a PanaVise (I think that's what it's called) to install the Sirius unit or side of dash. It looked like it would be a real good fit there. By doing it the way he suggested I wouldn't have to use the cigarette lighter plug. I guess it would be wired to the other radio or the fuse box or something. Anyway, does this seem like the best way to install the Audiovox unit.

Thanks,
Vic

The salesman is full of crap. A wireless FM modulator vs. AUX-in? He has to be kidding me...

try this for comparisons:

BenDee I don't think he was talking about an aux. adapter. He was talkikng about the new alpine adapter that hasn't come out yet.

I brought the truck in to have the installation done today. What they did is connect a short auxillary plug of some sort (about 6 inches long) to the tuner & then they connected wires from that aux plug under the carpet back to the stereo or the pnp or something (really not sure). (The auxillary plug they used to plug into the tuner had RCA connectors on one side & the other side plugged into the tuner.) I do know it's not FM modulated as it is connected to the auxillary of the tuner via some sort of adapter.

In order to access Sirius I have to press my source button from XM to AUX. Once I put it on AUX I then can listen to Sirius.

The sound isn't bad, but it's not as good as the XM head unit, but still it's very acceptable.

The installation was very neatly done using a Panavise & the Sirius unit sits right off the dash to the right next to the XM head unit. All in all, I'm very happy - I think. LOL

Thanks again for the help.

Vic, I have the opposite set with my Kenwood MP6025 head unit and Kenwood 902 Sirius Tuner. I have my XM Roady hooked up via the Aux Input and I dont think XM sounds nearly as good as SIRIUS via the DIN Connection. Then again, I have always felt that DIN connected head units sound better than PNP units even when directly connected via an Aux Input. There is just something about that DIN connection that gives it the very best sound quality possible. Since your XM is connected this way it probably does sound better than the SIRIUS unit connected via the Aux Input.

I do disagree that an FM modulated unit would sound as good as direct connect via Aux Input. This guy is full of crap about that. The direct connect Aux Input is as good as you are going to get without it being a DIN conected setup.

DAB,

The guy was talking about that new Alpine adapter that hasn't come out yet. I don't think it's the same thing as the way we hooked this up. I really don't know though.

The sound from the Sirius is definitely not as good though as XM, probably for the reasons you just mentioned.

In any event I really am glad to have both. Although I notice I stare at that Audiovox a little more than I should, looking to see what's on the other channels.

Hey I do have one question for you since you have a similar set up. If you leave both units on at the same time, does it do any harm? I like to see what's playing on the audiovox if I'm listening to XM, but when I switch back to XM the Sirius unit stays on- can that do any harm?

Thanks,
Vic

Do you know if this new Alpine adapter coming out this fall will work with their existing HU's?

I'm torn between the Alpine 9831 and the Clarion 745, they each have their +'s and one major -.

The Alpine is coming out with their iPod interface (very cool feature I want) this Sept. for their existing decks.

The Clarion looks nicer (display not as busy) and it has Sirius (which is the sat. provider I want).

If Alpine is releasing the Sirius tuner for their existing decks, I think the 9831 is the way I'm going, but if not, I might lean towards Clarion and suffer with not having my integrated iPod interface.

Sacrifices SUCK!

I haven't heard whether or not the Alpine Sirius tuner will require a new deck or not. I would think that it would be compatable with existing decks, but that is not guaranteed. I wish they would get the product out already!

I sent an email to Alpine asking them this question and the response came today.

Their websites haven't been updated yet, but I expect they will be soon!

John,
Great News!

2004 Alpine Head units ARE now compatible with XM Satelite radio AND SIRIUS
Satellite radio.
That's correct we are now supporting both formats.

Sirius is in development of a new tuner module that will directly
integrate into any SAT ready head unit.

Please visit the following links for more detail.

Also The Sirius/ Alpine tuner will work with 04 headunits and has a AI net pass thru so you can just plug in your other AI net products (Changer,Nav or I pod adaptor ect) to the Sirius tuner.

By the way the XM direct connect tuners do not have this ability. You will lose your AI net if you use one of the new Direct connect XM/Alpine tuners.

And thats just a start. This is gonna be a fun 3rd and 4th qtr.

Is there any info regarding the use of BOTH the Alpine XM tuner as well as the new Sirius Tuner? Will the radio (CDA-9833) recognize both units? If not, I might as well get a P2P immediately instead of waiting for the new tuner... I'd like to have both services controlled with the head unit (and maybe even the ipod adapter as well...)

Just checking in to see if anyone has any further info... delays... or if they can confirm the Sirius unit is pass-through.

Thanks.

A Sirius rep confirmed it is pass-through, so my guess is it is.

Hmm... XM AND Sirius with the pass through... that is an interesting thought!

Looks like this is a no-brainer. I'm buying the 9835 this week and sitting pretty until the iPod integration and Sirius hook-up comes through.
