Unlikely to cause issues with modern newer units. Wiki pointed out modern GPS week dates are now a 13 bit field extending the reset out 157 years. Not much different from the Y2K hype in 2000.

 

"GPS rolloverEdit

See also: GPS § Timekeeping

GPS dates are expressed as a week number and a day-of-week number, with the week number transmitted as a ten-bit value. This means that every 1024 weeks (about 19.6 years) after Sunday 6 January 1980 (the GPS epoch), the date resets again to that date; this happened for the first time at 23:59:47 on Saturday 21 August 1999[3] and will happen again at 23:59:42 UTC on 6 April 2019 and on 20 November 2038. To address this concern, modernised GPS navigation messages use a 13-bit field, which only repeats every 8,192 weeks (157 years), and will not return to zero until near the year 2137"

Huum, oddly their site says to sign up for their News letter to find out when the updates are.  Oh and your info may be shared to a 3rd party! Seems like a crappy way to get people to sign up for your News letter.  Why are no other companies sending this out?

I have 3 of their products and my Elite 5 GPS hasn't worked well since day one, really slow.
