Standard-Horizon GPS/Chart Plotter: CP150

A friend has a Standard-Horizon CP150 GPS receiver and chart plotter that was not working, and, since I also have one of these units, I volunteered to take a look at it for him. In the process I learned some interesting information.
The unit being examined appeared to work at the display head portion, but it never acquired any satellites. The antenna lead between the display unit and the antenna head had been cut during the process of removing the unit from the boat for the service inspection. I repaired the cut in the small coaxial cable as best as I could.
I checked the antenna connector on the output of the display unit to see if it was supplying voltage. It was. There was about 5-volts DC on the connector center conductor, as I anticipated there should be.
The unit gave no sign of getting any satellites and thus no position fixes. Otherwise it appeared to work. I called Standard-Horizon for advice. They were very helpful.
First, they offered to repair the unit for a flat rate of $99. If the antenna was defective, it would be replaced for an additional $90. Also, the antenna could be purchased from them and tried out to see if that would cure the problem. If the antenna didn't fix it, the unit and new antenna could be sent back for repairs for $99. If the problem was a simple replacement of a small coil associated with the antenna connector and supplying voltage to the antenna, that repair would be made at no charge. This policy seemed very reasonable.
Second, the very friendly and competent service technician/advisor on the telephone offered this additional advice: if the cable between the display unit and the antenna is cut and shortened, the unit WILL NOT work. They were told this by the unit's designers and they tried it themselves. If the cable length is changed the unit does not work.
Armed with this advice, our repair was hopeless without a new antenna. My friend is ordering the new $90 replacement antenna, and we think it may get the unit working again. If it does not, he will send it back for service, with a worst-case situation of an additional $99 fee.
The technician also offered another remedy to try: a hard reset of the unit. I'll pass on this information in a follow-up article.

The part number for the antenna for the CP150 is XUCMP0014.
This can be ordered from Standard-Horizon's parts department at (714) 827-7600 ext. 6800.

This procedure was sent from Standard-Horizon:
Procedure to reset and clear the CP150 firmware:
1) With power to the GPS turned off press and hold the ENTER key.
2) Now press and hold the PWR key.
3) Keep both keys pressed until the GPS screen lights up and you see the SYSTEM TEST page displayed, then you can release both keys.
Note: If the GPS is not able to be turned off using the PWR key you can turn power off at the breaker or disconnect the power cable, press and hold the ENTER key then turn the breaker on or plug the power cable back in.
4) Make sure that the RAM menu function is selected, then press the ENTER key.
5) A sub-menu will appear that has two selections; RAM test and RAM clear, move the shuttle point knob down to select RAM clear.
6) Press the ENTER key, a prompt will appear asking if you are sure that you want to clear the RAM. Press the ENTER key to confirm and a prompt will now appear that informs you that the RAM has been cleared.
7) Press the CLEAR key and you will be back on the SYSTEM TEST page.
8) Press and hold the PWR key until the unit turns off, then press and hold the PWR key until the unit turns back on again.
Please note this procedure will erase any saved user points such as marks and routes and will put all of the internal settings back to factory default. In addition the unit will have to reacquire satellite signals, which may take a minute or two. If you have a large number of routes and/or marks you may wish to save them to a User C-Card prior to performing the RAM clear. The User C-Card is a blank memory card that is available through your local dealer or can be purchased from C-Map directly by contacting them at (800) 424-2627.

Why not connect his unit to your antenna?

Wow, I would have loaned you an antenna. My CP150 antenna cable has a splice in it, and yes we were warned not to alter the length of the cable. (my father (a retired electronics technician) inquired several years ago after we determined that it would be nice to have the antenna cable 12" long to mount the antenna just above the unit. in light of their response, we have 30' of antenna cable wrapped up behind the unit.) My CP150 has been removed from my 15_Sport, but it still functions perfectly. (installed a new CP180i)
The source of your "no satellites" is likely a break in the cable which will appear invisible without very close inspection. That is actually why my cable has a splice.
I continue to be amazed at the service side of Standard Horizon. Although you are talking about a discontinued device, they are more than willing to repair it for a reasonable fee. If you end up sending them the unit ask them to flash it with the latest C-Map firmware.
As an alternative to the User C-Card, it is possible to connect the NMEA 183 output to a serial port on a computer and download the waypoints to a text file.

Standard Horizon has the best customer service in the industry.

My CP150 had the same problem with failure to acquire. After no joy with the hard start procedure a call to SH customer support ("Scott," I believe), a new antenna was on its way to me free of charge. This for a uit that was three or four years old at the time. The new antenna solved the problem and sold me on the fact that SH support is the best of the manufacturers.

Follow-up. Unit came back repaired with new antenna. Works fine again. I have not seen my friend recently as he has been having a few health problems. He survived dual knee replacements a few years ago and was going strong, but something has put him on the sick list for a while and I have not seen him in several months.

Just came upon this thread by accident after performing the RAM erase on an old CP 150C. Unit had refused to go beyound the "acquiring" phase when being started for the season. Took a short time to erase old routes, tracks, etc. and only a little longer to reinstall my preferred display modes. A very successful repair.
