From that site on the RER Software Update page:

Official Shipping Release: Version 1.220 - Latest Software Update

MyGIG Software Upgrade Version 1.220 (307 MB)

I'm not seeing a 2.043...

 

It is not listed on the side bar. Go into the thread/topic about software upgrades... Mine works fine... I used the NAV today again and the RER did great. It is a little tough to get used to coming from a REC
it is on page 10 I think in the

RER/REN/REW 2.043 thread under software upgrades...

 

Excellent, I'm downloading the file now. Here is the link for anyone else interested in downloading software version 2.043 for your RER MyGig's:

Maybe admins should make a sticky with the 2.043 update. A lot of forum members may want this...

good luck. Mine download like 1, 2, 3.. it was easy.
