Hello, I have a problem with my kia pro ceed ez. 08/2012. I have carried out the official update of the naviunite precisely according to the instructions. afterwards went up to volume and the last set radio station at all nothing anymore Since the problem is already known in principle, I tried the solution suggestions from forums. so ignition off and also fuse out. however, nothing changes. Only the kia logo. My dealer is also at a loss and speaks of an out The problem is, I bought the ceed last week from the dealer, but without a service booklet.. I know, not great, but is now unfortunately so. kia Germany puts itself across in some form something above the warranty. They turn themselves completely Stur. The dealer also did not get any further. The ceed is not even 2 years old and the navi unit is also not part of the maintenance. so it is not tested or maintained in any form during an inspection. ia now so simply push the responsibility away? After all, it was an official update after which now nothing can be done. That is definitely not the fine way and above all not customer friendly. I thank already now for hints that can possibly solve my problem.
