Im looking to upgrade the radio/Tape unit in this car to a used CD/MP3 one. I assume from what I have read that under the facia plate is a Din hole for a standard replacement unit which when combined with a facia plate will take care of the appearance. Its the wiring that concers me. Does the vehicle have standard wiring or do I need adapters ? if so which are cheapest , will the column/stalk still work, Im planning to keep costs to a minimum. All help appreciated. Chris
