Hi,

Need some advice/help...

I have a Lexus RX300 that is in need of an AUX jack for my iPod. It

has a proprietary audio system which I need to keep intact. I've

looked at a number of aftermarket AUX adapters from companies like

PAC, Blitzsafe, PIE, but these are a lot of money and and seem overly

complicated for such a simple thing.

My idea is to run the factory +/- CD changer signal outputs to a relay

that is also wired up to the +/- leads going to a female stereo aux

jack.

I have a number of questions about this...

1. Will this even work?

2. What kind of relay do I need (I assume double pole double throw)?

3. Does the relay have to be a special audio signal type of relay?

4. Will the relay automatically switch (and stay switched) whenever

the iPod offers a signal?

5. Do I need a mechanical A/B switch also?

6. Will I hear a noise "pop" when switching? If so, how do I avoid

that?

Any help would be greatly appreciated. I've talked with a number of

installers in the area who seem clueless about relays (go figure) so I

guess I'm on my own to do this. =(

Best,

D.
