I've been researching and looking at options on how to put in an aux input in the stock GM radio. It does not have XM, so I can't tap into that, I don't really want to have to slide a cassette in every time I want to plug in my Ipod.

The one thing that does lead into the radio that is an exteral unit is the Onstar.

I found that the Onstar goes into the back of the head unit with High and Low signal, but I'm affraid this is not audio quality. Has anyone looked at this as a means of adding a Aux input?

My other thought, so what makes the connection for the radio to switch to the cassette circuit? Does something get power or ground when the tape is slid in? Is it possible to add a toggle or even a relay that would allow the aux input to trigger the tape deck circuit to come on?

I have idea'* just no knowledge of the internal radio schematics

Thoughts?

And this, it is a little more expensive, but gives full integration, it plugs into the antenna port..

All of those links lead to the same option page to choose my car etc. Not real hip to the fm modulators either... we have strong signalled channels in my area that are in the 88.5 range

Ok, how about this?

That is really a nice option, but Lesabre is not on the list of vehicles that will work with it.

Looking like a indash radio may be best option... ugh..

Yea, I guess that is your only option. Sorry mate.

I did stumble upon this...... May be an option...sure is cheap! ( get what you pay for though )

Not too bad for the price. No aux input on the front. Your gonna need some cable to run from the rear of the unit to the front for input.

But, it does have SD card input. Find a 32gig card and you got plenty of space for music, videos, ****.. i mean, videos. lol.

if you dont mind replacing the hu, i got a sony hd, with front aux and usb with ipod control and tagging, for $130, and they give free mounting stuff.

The price of HU'* just floors me. I bought a nice Alpine back in 05 for like $350, no aux, no ipods then... it sounds nice.... but sucks in comparisson to these new options!
