[quote="cindy"]Is there someone out there that is willing to prepare the cord with the amp and give me instructions for a $$$.[/quote] One do it yourself solution that might not be too tough for you:

1) buy radio shack 12 v dc accessary outlet P/N 270-1556. this looks like a car cigarette lighter power connection taken out of the dashboard. It has a fuse built in, the ground wire has ring terminal for screwing to ground, and a tap connector for easy attachement to a 12 v car wire. (this is what I am using) about $15 I think

2) when everthing is set up, you plug your car adapter into your phone, the "cigarette lighter side" of the adapter into this outlet, and you will connect the wires to convenient wires inside the engine compartment, or under the dash, close to wherever you want to put the phone. The black wire is screwed to a piece of sheetmetal on the car, the other has a "tap adapter" that you just put around a wire carrying 12v from the batter and squeeze it together to make a connection.

It is good to use the car adapter that came with the phone because it has smart charge electronics so your battery will last longer than if you just connect the phone directly to the 12 V.

3) if you do not have the expertise to do the assembly, make sure you know where you want to install the phone, and take everything to an independent car repair shop or a radio/speaker install shop and they shoud be able to do it for you for about 50-100 dolllars.

Good luck, and of course I have to add "proceed at your own risk" :lol:

Just wanted to know what this was so I did not make a mistake!

Thank ya'll for the information. How is the air cleaner spot working for you? This would really be convenient for me, if the unit can tolerate the motor heat combined with the ambient temp here in the south, what temp tolerances can the i415 stand? Thanks

I would also be willing to buy one already set up, I am in Washington State.

Where are you located?

Install a 10 amp inline fuse to the positive wire on the cig lighter cord to protect it from short circuit.

I was reading the post on hotwiring with the external cigarette lighter but got completely lost on the 10 amp inline. Can someone explain this to me in detail?

Just wanted to update everyone since you were such a big help to me. I was able to successfully hotwire my i450 and run the wire through the firewall with other existing wiring. I just went to Radio Shack and bought an external cigarette reciever that had a 12 foot cord on it and connected a 10 amp inline fuse on the positive wire. I plugged the phone cigarette charger into that and tucked it away. It works great and has been up and running for 5 days straight at 1 minute intervals and HotGPS turned on. No problem whatsoever on the car battery.

Thanks for all the help,

Batteries for small cars (with reserve capacity 80 minutes) have about 35 Ah capacity . I measured the 12 volt current draw is 230 mA when charging my i88s. It draws 100 mA on the 12 volt when the cell battery is full. I calculated it takes 6 - 13 days to fully discharge the battery. Since the cell battery is full for most of the time, my guess is maybe 10 days or more to discharge a small car battery. This assumes your car battery is good.

If you drive a big car, the battery has more capacity (120 minutes RC) and it could last 50% more.

To prolong the life of car battery, we should not drain the car battery too much. So I think those who hot wire the charger and have small batteries should run their car at least every 3 days.

Correctomundo... :)

Skibum is correct 650 would be cold cranking amps, the reserve capacity of a car battery is around 100 amps. Accordind to the example you still would not have a problem with a hot wire to the battery.

[quote="Anonymous"]The battery that comes with the phone is around 800mah and it will last approx 6-9 hours running AT.
Find the amp hour capacity of your car battery and multiply it 1000 times. and that will give you the mah capacity of the car battery.
Example with 650 amp battery:
650x1000=650000/800=812.50 meaning it should last 203-304 days on a fully charged 650 amp battery.
I am no electrical engineer but I think this equates to No Problem hard wiring to a car battery.[/quote]

Unfortunately there is no car battery that has a capacity anywhere near that, so don't expect 9 months of operation. The 650 that you are referring to is cold cranking amps... The MAXIMUM draw that can be taken from the battery if fully charged. This has no relation to the capacity of the battery.
