Hi - thinking to upgrade the head unit in my 2005 SL55. one key component I'd need is either

https://navtv.com/products/NTV-KIT50...-s-opti-1.html

or

https://www.amazon.com/XTRONS-Optical-Replacement-Decoder-Mercedes-Benz/dp/B06Y673ZRV/ref=sr_1_1?keywords=xtrons+most&qid=1555954693&s=gateway&sr=8-1 https://www.amazon.com/XTRONS-Optical-Replacement-Decoder-Mercedes-Benz/dp/B06Y673ZRV/ref=sr_1_1?keywords=xtrons+most&qid=1555954693&s=gateway&sr=8-1

there is considerable difference in cost and wondering if anyone has experience with them or does know what the difference / benefit is? was going through many related threads but seems not being addressed so far. thanks much!

I think people go with NavTV or with the Avin unit. Not sure much difference functionally. Yours and the Avin are just Chinese clones of the NavTV unit.

Got most parts together I think I need including the 40eu10 antenna adapter. I've read conflicting things about the antenna cable. with an Alpine head unit and the AVIN MOST adapter as I plan to keep the Bose amp, is there a need to re-run antenna cable or not? is the stock antenna cable any special other then maybe the connector to the radio, which I think the adapter is for? (all this is in a 2005 SL55). thanks much
