I heard back from Harman Becker..
They said that this update will not work withREN (NON Nav) radios because the REN MyGIG radios have a different architecture inside them. You also can not update them to be a RER (Nav enabled) radio.
If you tried using this patch on a non nav radio it would refuse installation.
There currently is an officially released update for the non nav radio but they said that there are very few changes that the user would notice.
Send an email including your name and Addressand ask for a REN software update CD toSteve Montealegre at Harman Becker (
SMontealegre@harmanbecker.com) and he will send you an upgrade CD for the MyGIGREN.
So to answer your question.. This patch is only forMyGIG radios with Navigation.
