Thank you Mike Swanson for your prompt replies to all us Folks here on CN with this Rollover issue. Thank you so much as well for the Update that Celestron has now released to the Public the Firmware to fix the NexStar v4 and + hand controller! I will later tonight do the Firmware update procedure and post back the results.

Cheers

Don

Is it correct that one could simply purchase a new hand controller to fix the issue without an elaborate download?

Nope, they are usually several months (or more) behind as they are manufactured and boxed in China and shipped out to dealers.  Even the ones still in the box coming directly from Celestron are behind.  The update process is a little scary the first time but it isn't really that difficult.  The links I provided above should get you through it.

UPDATES

 

Shortly after I posted about the availability of the new firmware I discovered that the special version 98.22 for just those NexStar 8/9.25/11 GPS mounts currently displaying a date 17.5 years (not 20 years) in the past was not posted on Celestron's server.  I sent them a message to alert them but they have already left for the day.

 

Also, I neglected to mention that they are working on an update to NexRemote to add the new firmware versions.

 

And I have update this page of my website (and will continue to update it):

NexRemote gets a little love too? Boy that's good news (even if it is just a little love).

Hi Mike Swanson. Just wanted to let you and others know I updated the Hand Controller Firmware today GEM 4.22 for my Celestron CG5-ASGT Mount using my NexStar version 4 Hand Controller to get my Celestron CN-16 GPS working with the proper date.

 

WORKED PERFECT!!

 

Only thing I had to change was the time zone from Pacific after the Firmware Update to Eastern. 

 

So far doing a indoor fake alignment using my Planetarium Software CDC, all seems back to normal before this Rollover issue.

 

Thank you Mike and thank you with 2 Thumbs Up to Celestron for quickly getting on top of this and resolving the Rollover issue!!!!

 

Cheers

Don

I'm glad I was able to follow this topic and get updated with the official HC firmware release. Even though it spammed my email inbox. :)

 

Thank you Michael, and everyone for keeping us all updated. I have patched my HC with the latest 4.22 firmware update, and looking forward to moving on.

I sent an email to Celestron thanking them for what their doing on this GPS Rollover Issues......read below.

 

I want to thank you Celestron and your Tech Team for doing a phenomenal job addressing this GPS Rollover Issue!!

 

I have a CG5-ASGT Mount with the CN-16 GPS Unit and the NexStar version 4 Hand Controller.

 

I updated the new Public Released GEM  4.22 Firmware and it resolved the GPS Rollover issue! Worked PERFECT! Shows correct date now!

 

Thank you, thank you, thank you Celestron. Hats off to your Team!!! Fantastic job!

 

Kudos to Mike Swanson as well for his devotion and informative shared info to Celestron on the GPS Rollover Issues!

I have a CPC 1100 affected by this issue, with both a Nexstar* and a Nexstar+ remote. Used the workaround suggested in this thread in the meantime.

 

Just updated both remotes following Michael's instructions from his web site. Everything went smoothly. Pretty happy about it.

 

I'll report back when I get a chance to test this outside.

 

My thanks to Michael and Celestron!

Could someone who is in touch with Celestron determine when they will have new hand controllers available that will have software that circumvents this issue without updating? I had been planning to get a new controller anyway and would prefer to address both issues with a new one.

I have a Nexstar 5i and I noticed my gps has the wrong date also. I have CN16 GPS unit. My date is really weird. it says 10/8/15 but the number 1 in the year looks more like a "J" than a 1. I did leave the mount plugged in for over 24 hours to make sure the internal battery was charged. Time, longitude and latitude are correct, just the wrong date. My handset version is the older one. It says 2.2. Anyway, wondering if any other Nexstar 5i owners are seeing the same problem as I am. I did read through may of the posts in this thread. Sounds like I may need to get the newer handset that can be flashed and wait for Celestron to make their fix.

This really won't help you much since vendors may have stock on the shelves for well over a year.

Hi Martin,

This is a slight variation of the /5 date I report in the NXS 4.22 section on this page:
https://www.nexstars...GPSRollover.htm

As you can see there, Celestron has already released the fix. The new firmware for either a version 4 or NexStar+ hand control will fix your problem.
