I have my Mac mini in my car and a P1900. Recently (about the last month) I have seen my car strain to start (like the battery was getting low). Now, my battery keeps constantly dying on me. What is up with the P1900? It hasn't been doing this before my GPS receiver install I think, and I don't know what's going on. My battery is the original, but on a 8000 mile car, so I don't think that's the problem.
Also, if something is draining little by little, will a new Optima battery help me out any?
Hm - I hope optima batteries can do very well with a carPC, I've got a redtop myself. Here's to hoping - hope you resolve that issue since we're all doing MacCARs with the P1900 - can we have a picture of your setup? .
Same thing happened here. Battery went dead. reset the P1900 and jumped the battery. Worked fine. Now I have no more mini though. I miss it a little, but look forward to truely integrated navigation w/ my clarion unit.
