Been doing research for a SQ setup I am putting together in a 1992 Ford Explorer, and I have been looking at the Premier 680MP, when it came to my attention that it seems like time correction is not included on this model? If this is true, the Premier 780MP and 880PRS are around the same price and both sport time correction. Has anyone used both of these units and can attest to which they enjoyed better. Also, I will be using an iPod with this setup, and was wondering if the HU control on the 780 is worth it. Yes, I know this has been debated alot, so I am ONLY asking people who have used it as a daily driver.
