I recently purchased a 2000 RX300 and want to install my cell phone and XM radio. (I have the vehicle kit for my phone and modulator for XM) I have seen a few of the posts regarding placement of the XM, but have a few questions about the cell install:
1. is there a ready-made install for a vehicle adapter?
2. suggestions for placement of phone for a clean look?
3. What about an external antenna? or is there a hidden antenna built in already?
