JBOB 0 Posted June 8, 2005 My G/F has a JVC KD-SHX700 H/U and it works fine most of the time. BUT every once and a while it will loose all of the presets in the memory. This happens 2-3 times a week just from normal usage but also does it everytime you take the face off with the unit running. My H/U Sony CDX-F7700 is wired up in the exact same way red = ign +/Yellow = perm live/black = earth and runs fine and never loses the memory. The cars battery is fine and the charge system is good but I cant think what the problem is. Anybody else have this H/U and/or problems. Cheers J Quote Share this post Link to post Share on other sites
GIXXERUK 0 Posted June 9, 2005 i'd re wire using a different perm liveand earth point, it can only lose this if these wires are poor unless the h/u is at fault Quote Share this post Link to post Share on other sites
