SOURCE: ticking sound

We have a similar problem which was from a bad coed to receiver connection.
Try holding the point to where you hear the 'tick' and wait for the connection.

SOURCE: wish to update software

I did some digging in the files on my units drive. I have found a solution that gave me 2009 maps. With a little bit of computer file knowledge, you can register (for free in the developer section) at NAVTEQ. Their website is "". It took me about two hours of separating different database files but it was smooth sailing from there. Good Luck

How do I unfroze the screen of my Cobra 6000 pro hd gps? Nothing works

Try to leave it on with no battery supply until it runs completely out of charge and switches off. Only then connect it to your PC and see if it communicates with the software on the PC. If it's still frozen you need to restore it to factory settings.

SG2 model. I push power on and no screen.

Your battery is probably finished, get a new one at Battery Bob or elsewhere online, much cheaper than at SkyGolf

Lowrance LCX-19C GPS Receiver Problem

It sounds like you may have to send it out for service, but before you you do there are a few things you can try.

Low voltage can cause erratic behavior. Since you already wired directly to the battery, check the plug for corrosion.

Try unplugging the transducer cable to see if the display still behaves erratically. You wont see depth readings but you should still see the screen going black. If no erratic behavior with transducer unplugged then problem is in the transducer cable or the plug. A common source of failure is at the plug because the added stress of plugging and unplugging cables can cause the socket to twist slightly which can cause a short.

Make sure you have the latest software update.

How to see if your LCX-19C is already using version 1.8.0 software:
  1. Press the MENU button twice on your LCX-19C.
  2. Select SYSTEM SETUP.
  4. The software version for your unit is located under the line that says "LCX-19C" (ex. "Version 1.8.0").
  5. If your version is the same version listed above, there is no need to download the software.
If it is lower than 1.8.0 you can download the update from this link: LCX-19C UPDATE
Copy it onto a blank MMC card and install it in your GPS. The GPS should prompt you on how to install the update.

If you need to send the unit in for service click this link: LOWRANCE SERVICE

Good luck!
