I've just started looking at this type of thing for our Odyssey also (we have parking sensors but they annoy the hellout of me). To me that kit does seem fairly cheap, which could well be a reflection on the quality. We don't have GPS so were considering something like this - http://www.precisionvision.com.au/pa...reverse-camera. If was to self-install a basic set-up I would probably go for this - http://www.ebay.com.au/itm/350471628939. I would go for wired rather than wireless; it may be harder to install but you won't have the issues that invariably come with wireless.
