Read on a precise post that you can buy a computer saver at the FLAPS. Can't I just install a fuse from the battery to the disconnected side. So I still will have a ground an will not lose the presets. The radio has a 15 amp fuse so I thought I would install a 10 amp fuse. Any electrical people out there, will this work? 53 3100 root | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | | | | | | Joined: Nov 2010 Posts: 339 Shop Shark | | Shop Shark Joined: Nov 2010 Posts: 339 | No, after market, retrosound Zuma. | | | | | Joined: Feb 2002 Posts: 12,029 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Feb 2002 Posts: 12,029 | no it won't work, the only way to "save presets" is to keep the radio powered [with the correct size fuse] - a radio will always have a ground, even with the battery removed from the vehicle, it's the positive side that prevents the radio computer from losing its mind, and that's why the radio will kill your battery with a period of sitting

I know the radio is grounded to the cab and the cab to a ground to the battery. So, no ground if the battery is disconnected. How do you work around it? root | | | | | Joined: Mar 2002 Posts: 9,115 'Bolter | | 'Bolter Joined: Mar 2002 Posts: 9,115 | Why don't you ask the seller for a suggestion. | | | | | Joined: Nov 2010 Posts: 339 Shop Shark | | Shop Shark Joined: Nov 2010 Posts: 339 | I asked retrosound tech. and he did not know. The radio has a consent ON and a key ON only. Also with the key off the radio only draws 3.5 mill amps pre specs. I would think I could go as low as 2.5 or 5 amps. anyone?? root | | | | | Joined: Mar 2004 Posts: 256 'Bolter | | 'Bolter Joined: Mar 2004 Posts: 256 | Root...I set you a PM.
