Some people wanted to show vehicles to logged in users only.
Below you will find a description how to fix this. As you see I have attached a zip file with the corrected files.

Here are the instructions:

You will see three folder when unpacking the zipfile.
Place these folders on your desktop of whatever your like.

Go to you hosting account by FTP and search for the next folder:

../components/com_rdautos/views

Here you will find the next folder:
/results/tmpl/ (The tmpl folder is inside the results folder)
Replace the file from the result-view (zip) folder with the original
The file is called: default.php


../components/com_rdautos/views

Here you will find the next folder:
/detail/tmpl/ (The tmpl folder is inside the detail folder)
Replace the file from the detail-view (zip) folder with the original
The file is called: default.php


../components/com_rdautos/views

Here you will find the next folder:
/category/tmpl/ (The tmpl folder is inside the category folder)
Replace the file from the category-view (zip) folder with the original
The file is called: default.php

You're done with your hack.
The vehicles are now shown without prices unless logged in.
