Answered it myself and I am writing this for your information

I wrote to Garmin asking whether the new uconnect 8.4 for the 2014 GC would support this feature. Response:
Thank you for contacting Garmin International. Unfortunately the Garmin navigation in Chrysler's Media Centers will not recognize preplanned routes on a USB flash drive or import them.
This is very disappointing
. In my technical opinion it would have been an easy feature to implement, given that all necessary infrastructure is there already. May be there is no demand seen by Jeep/Garmin, which is however surprising given that for example BMW is investing a lot to make this feature available. May be I am the only one using it that way?
For our recent touring in Europe and Australia we have always preplanned tentative routes, using scenic side roads & tracks and putting many way-points in our navi for a single day's route. For this I have been using the fantastic free "Tyre to Travel" software with its Google Maps interface on my PC, saving routes in the navi's desired format and uploading them into the navi via USB. This worked perfectly with our TomTom handheld, and also with a rented BMW 5GT's built-in navi. In the BMW you can import many preplanned routes via USB into the car's navi.
Garmin's info seems to mean that in order to apply this process in the future I should either
(i) buy a BMW ( I would prefer the GC but may be I should give it a thought), or
(ii) stick my handheld Tom Tom navi to the GC's windscreen above its new built-in 8.4 uconnect system, which you might agree would look ridiculous, or
(iii) try transferring the planned route into the GC uconnect by sitting in the car and punching multiple way-points in each day. However, the present GC navi system only accepts 8 way-points max, and I have no info whether the new one allows for a higher capacity. With the BMW system, I could use 50 way-points or more for a single route.
Would anyone care to share with me how you have managed to plan a route with your present GC navi when for example you wanted to use specific roads & tracks different to what the system would recommend to you normally for traveling from A to B? Or is the Chrysler/Jeep navi really only meant to go from A to B with the route options chosen by the system?
Thank you for a response!
