Default Weak RF in Chevy Venture

Hi,

I've installed an SP-R2 in my 2001 Chevy Venture. I'm getting really weak RF reception, which improves markedly if I lay my fingers on the antenna grid just above the rear-view mirror. The receiver is mounted just under the cupholders in the center stack.

Can I do anything to improve the RF signal?

I orignally intended to use the AUX inputs which are in the center stack, just above the VCR housing, but I put the kibosh on that after I found out that audio would not come out of the front door speakers, and that the head unit had to be switched off, too.

I'd rather have a hard-wired system. Can I somehow patch the Sirius recevier into the AUX input on the factory head unit? Since this is probably for an external CD changer or something, I imagine that an adapter of some sort will be necessary. Note that this is a different AUX than what I tried previously, which is apparently linked only to the rear-seat entertainment system.

Thanks for helping a first-time poster!

Best regards,

Tim ==

What about the FM Direct Adapter (aka Wired FM Modulator)? They sell them at $20 at http://www.tss-radio.com

Thanks a bunch. I think I've found some AUX adapters, also...but they're double the cost of this solution. How is the quality of the sound affected through the direct adapter, as opposed to a line-out connection?

I have a GM vehicle using this solution and its just like having it hard wired,look close to the firewall on the passenger side,you should see a place to connect this(antenna connection) without tearing your poor vehicle apart(look under the carpet next to the firewall.

When using one of these direct RF modulators, is it difficult to find a clean frequency in a crowded FM market?

Post FM Direct Adapter

The FM Direct adapter is a must for the best RF reception. The reception in my 1989 Grand Marquis with Starmate replay has had alot of static. I just installed the FM direct adapter and it provides the best static free. I even have the fm preset on a major local radio station, and since the vehicle antenna is disconnected it transmits perfectly, then if I happen to be in the car without the sirius (which is almost never), i dont have to worry about changing the station.

Summary: For best reception, use the FM Direct Relay.

The FM out on your sirius switches a relay that removes the antenna from your car stereo and sends the signal directly to your FM stereo car radio.
You can even put the sirius on say 95.5 a radio station in your area and when the sirius is NOT on the station will play .
