Here's the solution I received from Garmin:

Thank you for contacting Garmin International.

I apologize for the inconvenience with your unit not acquiring satellites. It will need to come into us. I have set up a RMA for you to send the unit in. I just need for you to put the following information on the shipping label please.

Garmin Int'l
RMA ZW 0000000
Dock Door #20
1200 E 151st St
Olathe, KS 66062

Please send the unit in by itself. Once we receive the device from you, it normally takes 7-10 days to get it back to you. If you have any other questions, please let me know.

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.

I Got it!
I finally got my HTC TyTN II yesterday from Dubai.
First thing I wanted to test was the GPS. It did not work with: TomTom6, Google Maps, Yahoo Go.)
I was surfing around to find something that would help me out and have noticed that many people have the same problem.
Many people (Like me) did not know howe to setup the GPS.
Many people are saying: "You have to put it your GPS settings in Com 4 and the Baud rate on 4800 and it should work.
Well mine didn't work with those settings. (Along with other people.)
I had played with the External GPS option (Don't do this cause setting something wrongm ay cost you a HARD-Reset.)
I Was lucky that mine worked again after a SOFT-Reset. So watch out!
The standard GPS settings! (If you have changed it, Soft-reset your phone and set it up as these pictures show.)

Why am I doing this?
People buy this phone to make use of it. When something does not work why buy the phone then :S
Hope that this may help a lot of people on here and other forums, communitys & websites.

Here is my story of how I did get my GPS to work:
1. Download the GPS addresses by using QuickGPS (Start -> Programs -> QuickGPS).
(This will download info of what your GPS Reciver needs to connect to the satalites.)
2. Download a free (Well half free, You can also buy this application it will give you some extra options, but we don't need those extra options.) tool named: GPS Test. ( or at
(This program will scan all your mobiles com ports and Baud rates, To see what your real GPS settings are.
In my case they were: COM PORT: 4 - Baud Rate: 9600 (Notice it ain't 4800. Usaly it shows your settings with a pop-up.
When It doesn't Go to "Menu -> GPS Settings", There it will show you you're GPS settings.)
3. Install TomTom 64. Download your free map.
5. Go to the GPS settings.
(Set-up: Other NMEA GPS-Reciver -> GPS-Baud Rate -> Com. (Select the Baud rate + Com port from what the GPS Test did show you.)
6. Now wait.

Suggest COBRA get off their duffs and gets these GPS's updated. Mine is so far out of date, I have no idea where to travel by this piece of junk.

Cobra 4000

Plug the unit it and leave it plugged in for a while, make sure to keep it off.

Let the power stay on the unit for a while, like 20 mins or so and then try it again.

I think that the unit has an internal battery like your alarm clock and when the power goes out the battery takes over. I beleive in your case the battery may be dead.

The same thing happened to mine.

Let me know.
