Hi,

first of all thank you very much for this fantastic page :) . I’m really impressed about the discussions and the solution I saw over the last few years. But the often asked questions were not really answered for me yet.

Is it possible to connect an iPOD directly on the OEM stereo, without opening and modifying the radio?
And is it possible to control the iPOD over the OEM stereo, while the POD is remaining in the glove box?


Since Monday of this week I can say:

It is possible, the sound is great, the control works perfect and the iPOD charge while connected!!!!

I found the solution in the American LOC. There is a little company in California called Grom Audio. They produce like Dension (ice link) AUX and iPOD adapter for OEM stereos. You can imagine that couldn’t believe my eyes when I was checking the compatibility list and found the IS300 from 1999 – 2005 on it.

----------------------------------------------

My package was delivered about one week after ordering. For $79,99 the package contents:

- Car stereo adapter in plastic enclosure
- OEM compatible harness to connect to the back of the car stereo
- iPod dock in cable (gen 4 and up iPods)
- Installation manual

I installed it in just one hour due to the OEM compatible harness an it just works!!!!!

The OEM stereo knows right now the following things:
  • FM button -> regular Radio
  • Tape button -> Tape
  • Disk button (first time pressing) -> internal CD-Changer (on the left side of the display you will see then “CD”)
  • Disk button (second time pressing) -> external CD-Changer -> Grom Audio iPOD interface (on the left side of the display you will see then “CD1”)
Even if your internal CD changer has an ERR3 fault it should run because the solution activate the EXTERNAL CD Changer control.

One special thing is maybe interesting for people who are planning to buy an iPOD but do not own one so far. They can also order the IPOD interface from Grom Audio and and add an extra cable called (AUX RCA cable + 3.5 mm phone jack (Cable-AUX-C)) for only $4.99

http://indashpc.org/new/accessories/cable-aux-c.html

This cable can be plugged into the iPOD interface box – instead of the iPod dock in cable – and allows you to listen to music from your regular mp3 player (without control from OEM stero for sure).

OK, let me show you some photos:

I hope this helps you to get mp3 in you car without loosing the original design inside of the car. If you have further questions, please ask.

P.S. My Car has a 9 speaker Stereo with satnav and nav seems to work with this solution :-))

Does your car have satnav? Do you know if this device works on cars with satnav?

This has always been the pitfall in the past for this type of solution, as the extra slot (for the MD player) that is used by these devices is taken up by the navigation input..........

I might have to drop them an email as that is a very attractive price :)

Hi,

yes my car has satnav!! I have a fully equiped IS300 Sportcross. The Stereo has the OEM external Amp and 9 spakers. And the GromAudio Interface integrates perfect - no Y-connector needed.

While I was looking for a possibility to connect my MP3 Player on the OEM Stereo, I rebuild the stereo and found out, that only one harness was equiped with a plug.

The relevant 12 line plug for all external CD Changer and Audio stuff (marked red on my pictures) was empty. So it was easy to plug the grom adapter inside and it just works!!!

I will add some photos of different radio versions. You will see that all the radios have this place to connect.

Best Regards

Sonnet

Sonnet,

that was a great post (so great it almost sounded as if you were on comission ;) )

But it's come at the right time for me - I've got err3 and hate tape/fm adapters for ipod but love the stock headunit look.


I've gone ahead and ordered one.

I have sat nav so will report back when I get it and let all know how it goes.

that seems.... well.. brilliant!!

works out to about £50, which is a little on the high side, but if it works like it say it does, not a bad price.

let us know when you get it Hando, and how well it works.

what i want to know is, if i hit the "next track" button on the unit, will it actually work?

Allegedly - if you have a 4th gen ipod or higher - not only that'll work but selecting Disc 2-6 will cycle thru your first 5 playlists.

:o thats very cool!!! i might start saving up for this one! my current solution, a mixture of both a tape adaptor and an FM transmitter [one for london, one for north country] is starting to frustrate me!

Willdo - part has been ordered - will report back how it goes with a 2002 IS300 stereo with sat nav and err3 (if it'll work with that it should work with anything)

will be interested to hear about this, i too am one who has the sat nav, and Err3 looming! i also have the older stereo with the bottom loading CD player.

could someone let me know if you lose the audio from the sat nav once you've tried it.

maybe we could do a group buy as it may prove to be very popular

Hi all,

thank you very much for all the replies :D

I can affirm you that I’m not on commission of Grom audio. Since all of you I was only looking for month to a suitable solution to bring mp3 in my car and keep the original design. So I'm just a satisfied customer!

Right now after almost one week of testing I can say it’s the ultimate solution for me:

Original design, no cables hanging around, almost full control of my iPOD nano 8GB third generation which I charged while connected and….a really cool sound!!!!

I have a few things that I would like to add. I hope they will be helpful for you:

After I found out that the Grom box was working fine the next challenge was to find a place were I can store it. After searching an testing a little bit I remounted the OEM stereo, lifted a little bit up and stored the box in the empty room o the right hand side inside of the middle console (on a RHD car it might be on the left hand side). The place is perfect because it's close to the glove box where the player is stored and you can grab from the passenger side behind the middle console and change the iPOD cable against the regular AUX one if needed.

The second thing is that if your using the interface in the simple mode (disk 1) – in advanced mode you can surf with your stereo thru the play lists 1-8 - you can select manually on your iPOD every other play list over #8 for example play list 18 and navigate then with your stereo controls (track back and forwards) thru the tracks.

And the last thing is more iPOD nano 3. Generation specific. I’m an absolute electronic music fan. Due to this reason it was always a pain to listen to gapless mixed electronic sampler in mp3, because you hear a short break after each track. Right now with my new nano gapless play is POSSIBLE :D

So electronic beats, gapless played for hours in my Lex with full control……could it be better?

Best Regards from Berlin

Hi,

about the ERR3 problem, I can tell you how I deal with the problem.

I do NOT load any CDs in the internal CD changer. If I press in radio moder than the "Disc" button on the OEM stereo, the radio goes DIRECTLY tho the EXTERNAL CD changer mode "CD1". Due to this reason, it seem that you dont have to care about problems with your internal cd changer. Just dont fill it with CDs.

If you use the Grom adapter there is no need of a CD inside of the stereo to listen to your external music source.

I hope this information will helb everybody with a faulty original stereo.

Best Regards

Sonnet
