So I installed a Pioneer 4100 nex a while back and decided it's time to add a backup camera. Thinking of putting it in the bumper below the spare and am looking for some options people used. Not really interested in the ones that go in the spare tire. I know http://www.amazon.com/Gino-Waterproof-Reverse-Backup-Camera/dp/B00B2ZD7OS/ref=sr_1_1?s=automotive&ie=UTF8&qid=1446478550&sr=1-1&keywords=flush+mount+backup+camera seems to be a popular choice but what I'm really looking for is one without the parking lines since it seams most people have issues with them not pointing the right way, and the head unit has guide lines anyways. Any suggestions?
