Hey guys, my buddy just bought a 1993 ES 300 and its got a couple gremlins I need help with. First is with the radio. The stock power antenna went out so a regular mast antenna from Auto Zone was installed in its place. The stock radio plays tapes just fine but when you switch over to the radio you can barely hear it, if at all. Its like there is zero reception and that is with the volume **** turned all the way up. It did this before the antenna was replaced. I am stumped. How can I fix this myself?

Also, the car was equipped with a stock cd changer in the trunk. We don't have the sleeve that slides into the changer. Is there a workaround to use it, or maybe a cheap sleeve replacement?

Any help would be EXTREMELY appreciated.
