Does this work with a 2003 Suburban?
A shopper on Jan 1, 2015
Best Answer: Hello,

The ISBT21 is a Add-On module for the iSimple Gateway Interface. If you have, for example, the iSimple Gateway PXAMG, then the ISBT21 will use on of its inputs for the ISBT21. If you do not have the iSimple Gateway PXAMG, then you will need to get that, along with the iSimple PXHGM3, Then the ISBT21 will be able to integrate into your vehicle.

Is this kit all I will need to play music from my Samsung smart phone through the existing factory stereo in my 2004 GMC Sierra?
Kevin C on Jun 26, 2016
Best Answer: Works great in my 06 escalade, I also bought the Bluetooth module to go with so I don't have to fumble with plugging it ever and the benefit of hands free calling.

I have a 2003 chevy silverado with the bose system, but I don't have satellite radio. Do you have a kit for that. Both option that came up say you have to have a satellite radio option?
A shopper on Jan 15, 2016
Best Answer: Hello,

We highly recommend getting into a new headunit that has the features you seek. It will be far more economical and convenient. Nevertheless....

Below is a link to the PAC GMCSS2. It is ONLY an integration harness and requires one of many other parts to work exactly the way you wish for the feature to work for you. Below the link is the manufacturer's link, that will outline what is needed. Unfortunately, we no longer carry any of the parts outlined.

Will this work on a 2011 tacoma with the basic radio and is an easy install?
A shopper on Jan 16, 2015
Best Answer: Hello,

The ISBT21 is an Add-On for module for the iSimple Gateway Interface. Of which, if you do not have the iSimple Gateway ISTY571 then you will need it for the ISBT21 to interface with. We cannot establish the 'ease of installation' because that varies from person to person.

I'm looking to buy the iSimple ISBT21 BluStream for a 2008 Ford Expedition EL XLT. I see that it is compatible. Is this all that I need to allow for Bluetooth capabilities on the factory car stereo?
