Hi,

first of all thank you very much for this fantastic board! I’m really impressed about the discussions and the solution I saw over the last few years. But there is one question left which was not really answered for me so far.

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 stock headunit buttons, while the POD is remaining in the glove box?


Since last week I can say:

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

There is a little company in San Mateo (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.

Grom audio - digital interface to integrate PDA into car audio system - product

I knew from former searches to find a possibility to connext external sound sources to the stock headunit that only one harness of the backside of the radio was equiped with a plug. The relevant 12 line harness where GromAudio wants to connect their interface were empty (it's marked red on the attached photos). So it was easy to plug the grom adapter inside and it just works!!!

So connection is possible :bigSmile: Let have a look to the features (quote from the manufacturer web site):

Quote start------------

Toyota / Scion / Lexus GROM for iPod interface(GROM-IPOD-TOY)

-Original harness to connect to iPod (dock in cable)
-Original harness to connect to the back of the stereo
-Direct connection to the car stereo. CD quality sound
-Full control from car stereo or steering wheel

-In-dash 6-CD will remain working !

It provides direct audio interface to a car stereo via the CD changer port. GROM Audio interface insures CD quality sound from iPod to car stereo speakers. It allow to "fool" your stereo into thinking that fully featured CD changer is plugged in. This way you can have thousands of tracks divided into playlists or full shuffle mode if you wish.

  • Direct connection from iPod to car stereo provides CD quality sound
  • GROM Audio translates button presses from your car stereo or steering wheel to the particular command iPod can understand
  • Enables easy integration into the car system. Place it anywhere, control from the car stereo
  • Charges iPod while connected

Quote End-------------------------

My package was delivered (to Europe) 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
  • Installation manual

I installed it in just one hour due to the OEM compatible harness and 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”)

If no Disc is in the internal CD changer you only need to press ONE time on the disc buton to switch from FM or tape to your iPod or other external sound source.

Even if your internal CD changer has an ERR3 fault it should run because the solution activate the EXTERNAL CD Changer control. For the electronic it's not relevant if the internal cd changer works properly or not.

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

In Dash PC - Accessories

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).

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 on the right hand side inside of the middle console. 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.

Another 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.

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.

The best – even it’s more iPOD nano 3. Generation specific - at the end. 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 (file). Right now with my new nano gapless play is POSSIBLE

So electronic beats, gapless played for hours in my Lex with full control over the stock headunit with a nonvisible iPod……could it be better?

Best Regards from Berlin – Germany

Sonnet

P.S. My Car has a 9 speaker Stereo with satnav and nav works with this solution a usual :)) When beeing in iPod mode with satnav running, the driver side speaker fades out the music from time to time, so that you can hear the voice of the navigation lady as usual. After the orders were given the speaker switches back to the iPod music. Wonderful!!! It works like factory build!!!

Hi,

what's wrong about being enthusiastic on something? Due to the reason I'm located in Berlin / Germany my home board is the LOC Europe in German where I'm posting usually. But I found this might be interesting for the IS community. But instead of a warm welcome after sharing my solution with you I must read that people think I'm advertising something...brilliant!!!!

Let me underline it:
Grom Audio is located in Las Vegas and I'm in Berlin Germany
I'm not connected with them,
I don't sell their stuff and earn no money by selling it...

I'm just an excited user!

Yes it's my first post on this board. Boards are central platforms of good advises and help topics for me, so there was no reason for me just to post without having anything interesting to say except, that I'm driving an IS300 Sportcross with LPG. So I decided to post something helpfull....

I've read for month and month in the boards to find a solution, but if someone founds a possible one they post a link and write something like " Found this, is anyone out there who wants to try it out?"

In most cases you will find then a long discussion about all the problems or missing features the solution would have - WITHOUT using the thing.

In this case I found a short hint in the LOC USA AND just bought and tested it for more than two weeks right now! I can say it's the best solution I saw for years, because it's cheap and works as it should do.

It's everybodies own choice which solution they choose. Mine is this.

Sounds identical in form and function to the Soundlinq SLI unit.
I agree, also..the post does read like an advertisement. No offense intended.

Hi,

my IS300 SportX is from March 2003 and has right no about 48.000 km on the clock. The car is black with black leather, sunroof, automatic shifting, this sportcross specific chrome rings at the rear fog lights, black xenon headlight and....LPG (fluid gas) with an extra tank - due to the reason that regular gas is so expensive in Germany -> 1 litre cost 1.42 Euro

Best Regards from Berlin

Sonnet

@all who think my first post is an advertising

IT'S NOT!!! I thougt that the forum on myIS is interested in user experience and innovation and installation manual are welcome. Unfortunately it seem to me, that you have to place 50 post before you're allowed to write something like me without people think you would like to sell something.

@ All others who are interested

If you have questions - just ask. I will try to answer you from my experience :)))

I think it's something pretty cool. This unit is similar that the one guy used to hook up his iPod and aftermarket navigation to the OEM radio.

If I didn't have the AVIC-Z2 and wanted to retain my OEM radio, I would do this in a heartbeat to keep the stock look.

Welcome to the board by the way, Sonnet! I hope you too find some valuable information here!

not to thread jack, but does anyone know what kind of a connector is used to go from the grom unit(pictured above) into the mp3 cable(also pictured)

I'd want to get a Y with those connectors to plug in an ipod and xm radio

Great find by the way!!!

The connectror from the Grom box to the external sound source (iPod via dock cable / other devices via AUX RCA cable + 3.5 mm phone jack) looks like a regular 8 pin mini-DIN female connector like you can find on these ATI All-In-Wonder graphic cards for Video output. So the cabels have then 8 pin mini-DIN male connectors.

It's an interesting idea to build or buy an 8 pin mini-DIN Y-cable to connect two cables (the iPod dock cable and the regular AUX RCA) at the Grom Box at the same time to be open for other devices beside the POD.

But I'm not sure im the GromBox can handle signals from two different sources at the same time. That's something you have to ask directly to the manufacturer.

Best regards from Berlin

This seems very interesting. This may be a solution to my problems. I guess navi can wait for now. I'm interested in finding out if this will work in this IS300s in America. I know there are slight differences between 01 and 02+, and maybe a difference between regions. Can anyone confirm the plugs in the back.

Hi,

mayby this harness compatiblity chart I found on their american distributor site

http://gromaudio.com/docs/compatibility_chart.pdf

Due to the reason Grom Audio a small american manufacturer they might have digned at first for the american market. I was lucky that my car hee in Germany had the correct connectors on the backside of the radio

Good luck

I am interested in this but have a few quick qs for you.

1. It looks like you needed to modify the connector that connects to the HU, was this something you ran into as an install issue or is that how it comes from Grom?
2. Will this charge the Ipod as I play it?
3. How long is the supplied cord that connects from the HU to the Ipod (black in your pictures). Reason is I want to put my ipod in the center armrest cubby (think under the arm rest) would this be possible?

thanks and +rep

@mkiiina,

thank you for your questions :) I will try to answer them:

1. It looks like you needed to modify the connector that connects to the HU, was this something you ran into as an install issue or is that how it comes from Grom?
OK this was my fault. I've add a photo where a cable was seen that I've done by myself and that was fitted BEFORE I received the Grom box. The reason why I've post the photo was just to show you gus that the relevant harness is usually unplugged and can be used for the Grom adapter.

2. Will this charge the Ipod as I play it?
Yep :bigSmile:

3. How long is the supplied cord that connects from the HU to the Ipod (black in your pictures). Reason is I want to put my ipod in the center armrest cubby (think under the arm rest) would this be possible?
The iPod is NOT connected direct to the HU. First of all you have a pretty short - car specific - cable from the HU to the GromAudio black box. This black box can be stored below the radio inside of the middle console. From this black box an iPod docking cable (my picture just shows the alternative RCA AUX cable to the iPOD docking cable) runs directly into the iPod. This cable is long enough to store your POD under the armchest.

But why do you want to store the POD there? If you are using the Grom box you can control the first 8 Playlist on you iPod over the stock HU without. I placed my iPod in the glove box. This works really cool, because nobody can see the device and I just can leave it in the car when I park somewhere...

I hops these answers help you!

Have fun
