First time poster! 2012 Genny w/ tech. We are planning a major road trip this summer and wanted most current maps available. Read these series of posts and got uncomfortable. Jumping to the end of story, it is complete, everything appears to be working correctly, all existing data remained intact.
Research. The dealer that we bought the car from is not an Equus dealer and had never done a DIS upgrade. Told the service manager that based on posts on this site, was not comfortable being their first. Sought out an Equus dealer with experience and was quoted $350, includes price of authorization code from MNSoft and dealer labor. Said upgrade was 03.00.00 2012.04.14.01. Told him that I looking for V5. I called MNSOFT and was told that all software revisions to date start with 03.00... Original dealer service manager called back and told me that he had reviewed the update procedure and offered to review it with me. We reviewed the procedure and agreed that it was straightforward. He said that he would do the install personally with no labor charge so that he could determine what labor charge should be. I agreed.
Install. I offered to sit and babysit the car during the install. He agreed. The upgrade is a package of 6 disks, 3 operating system & 3 map data. Only 1 operating system disc is used depending on car configuration. 1 of the 3 is Equus only. Of the 2 remaining Genny discs, which one is used is based on the retrieved HW Device ID. You select from yellow or orange but the orange is very "weak", very little red, almost yellow. They are also identified as "Type 1 " or "Type 2". I mention this because the disks have a red caution label suggesting system damage if the wrong disk is used. This was the only element of the procedure that might explain some of the problems reported here. Operating system install took 1 hour. 3 map data discs took 3:15. 4:15 plus :15 for system checks at end. There was no downtime. It could not be done more quickly.
Results. Everything works, all data is intact, nothing looks different. some graphics changes have been reported but I have not seen them. I have no idea what the operating system revisions did.
Cost. I paid $200. Service manager is trying to decide how many labor hours need to be priced in. Future price will be based on that decision.
Editorial comment. Genny replaced
Infiniti M45 with DVD based nav system. Upgrade for that car was buy discs, about $200, select quadrant of country that you are in, load disc. 10 minutes max. Disadvantage, keep discs in car so that you can load new quadrant when travelling.
The DIS hard drive system should have an advantage over the DVD system in that significant changes can be made with the software, much like upgrades to computer operating systems. It does not look like Hyundai is taking advantage of this yet.
