Maybe stuff like this, appropriately titled should be going in the technical /maintenance section? It's good info & photos that tends to get lost in general threads and then is impossible to find again at a later date.
In my day a rubber grommet sufficed. Progress??
agree but, the Grenadier system looks much more complex: internal & external plugs bought together to compress a rubber grommet under tension
The larger the grommet, the harder it is to keep it in place. I don't really think of grommets as removeable, in the sense these drain plugs are designed to be on, possibly on a frequent basis.
@Jean Mercier ...it may not only be the music file format, but also the format of the storage medium: The HDD in the iPod has most probably been formatted FAT32, not NTFS . The iPod HDD also has a max size probably of 128 or 256Gb. The Ineos audio system isn't the top of the range
(otherwise they wouldn't offer a "premium"system in the USA spec)...many systems in this category are capped in their ability to read file storage media greater than 256Gb and require a FAT32 format. 
I already could solve the problem, but posted my solution in a new thread yesterday: "Connecting a USB-A stick or drive to the infotainment screen"@Jean Mercier ...it may not only be the music file format, but also the format of the storage medium: The HDD in the iPod has most probably been formatted FAT32, not NTFS . The iPod HDD also has a max size probably of 128 or 256Gb. The Ineos audio system isn't the top of the range
So... check the USB is FAT32 format and 256Gb or less total capacity...
PS glad you arrived safely in Hungary! enjoy your visit!
You are right, I have posted it again with some text editing in the technical section.
It seems that your grenadier is rapidly approaching the level of an original defender.
Just showed it to my son sitting next to me on the couch in Hungary, he is half Brazilian
Any more pics of your gren?
Will get some more tommorow!
We need a thread JUST for pics of the IG. Maybe a Build / In The Wild (photos only)
Looks awesome. If I do end up getting a Gren (jury is out) i will probably go with magic mushroom as well. And likely get some red accent wraps just like IA had in many of the promo pics.
