I have emailed the guy from planetworld he is very helpful, to a point, the unit with GPS included is about R15k inc installation last time i checked (recently) but after several emails with him replying with the same thing I eventually gave up on trying to find a price for the unit without the GPS included, I would suggest looking at a nice double din unit from Sony Panasonic or JVC from a decent car audio place, should only run you about R7-R10k then
