You dont need a battery with the garmin 15-L because it can keep the info for 20 days without power.

here are some pics of the install I did

Now that is no fun whatsoever! But then again, soldering is second nature to me. Personally, the Trimble and Motorola modules are my favorite. But they require more soldering and more trouble to get working. The performance of the Lassen SK2 is really damn good, as well as the ACE III. The motorola modules require more power, but work just as good.

jcdillin,

It must have a memory backup capacitor.

Thanks for the answers.

I have some open usb pins on the motherboard. Do I need to put anything inline to wire to the usb power?

nothing as long as it's 5 volts+, you can put a fuse between the module and power if you like. that is what I did.

**IntellaWorks** · 03-09-2005, 09:23 AM

You could throw a fuse in line, but because that line is being monitored by the ATX power supply, it should never go OVER 5v... I personally didn't use a fuse.

so if I was to get this, I would still need an antenna and software?, btw, how are you guys able to mount it on the roof? with wire coming out of rear window, wouldn't that leave leaks?

**IntellaWorks** · 03-09-2005, 10:34 PM

Vehicles windows typically have flexiable weather stripping around each window.. and no leaks occur because this weather striipping prevents the leaks..

hey Intel, what gps software and antenna are you using ? how does it work for you so far?
