I decided to try one more time contacting Jeep support regarding the map updates. Still waiting to hear from HERE. Looks like I'll be using the NUVI for a while.
Jeep support response to my original query;
"Thank you for contacting the Jeep Customer Assistance Center regarding
your 2014 Grand Cherokee.
I regret the problem your vehicle has experienced with the navigation
and appreciate the time and effort you took to bring this matter to my
attention.
In regards to updates for your media center you would have to speak to
HERE as they provide all software updates to our media centers. They should be able to provide a timeline when you can expect a software update.
Comments like yours are one way we have to learn of problems that may
develop and improvements desired by customers. I will certainly pass on
your suggestion of using Garmin for navigation services.
Thank you again for your email. Should you require additional assistance,
or have any new information to provide, please reply to this email message or call 1-877-I-AM-JEEP (1-877-426-5337).
Sincerely,
Linda"
My follow-up;
" Thank you for the quick response. I have contacted HERE on several
occasions regarding an update for the Navigation maps, with a poor
response each time. I have attached my last two responses from them. When I check their update web site all that is shown there is a cryptic message. Neither contacting them or their web site provides any useful information regarding when an update might occur, what will be in it or why it has been delayed for so long.
Given that the use of HERE was decided upon by FCA/Chrysler/Jeep, I
would think Jeep would have interest in finding out what is causing their
customers such poor service. I have sent another query to HERE and have
also attached that email. I am now using my eight year old Garmin NUVI
for navigation in our Grand Cherokee; it is up to date with maps from the
beginning of the year. If an eight year old navigation system can be
kept updated I find it difficult to understand how my 2014 Grand Cherokee has to continue to use maps that are three years old. In my opinion, Jeep
needs to become involved as it is there customer base being inconvenienced."
