GROM USB-HON1 issues with 2004 Acura TL with Navigation/XM

[nostra]

Order id: #20-101905-xxxx. May be I was shipped a kit with different version of F/W (like in non-Navi/XM type) as it was initially recognizing only the CD-Changer mode and was playing the songs from my IPod with a very low volume and lot of hiss. I then tried to upgrade the F/W from GROM's support site (through USB) and it now works in XM mode.

However there are 3 issues now:
1> Text does not display on the screen when playing through IPod or USB as advertised! Instead the XM station info is being displayed.
2> Steering wheel controls does not function either as advertised with their latest F/W
3> Most annoying: XM still plays in the background with a very low volume though. But when you crank up the volume you can clearly feel it playing in the background.

I am a member of Acurazine forums and I can find no posts for this adapter installed on a TL. I do see lot of people inquiring about this for a 3G TL though. My review there would definitely encourage more people from the forum to go for this one and I would sure recommend autotoys for the purchase

Any help is appreciated!

You must disconnect the factory xm completely in the trunk for it to work and stop bleeding.
