Is it because of the simple fact I did not use a microSD card? or is there something I did wrong?
All you did wrong is assume you could do the same for the unit, my suggestion was only for the card. Spend a few bucks for a small microSD, follow my previous advice and you won't risk bricking the unit. It's only a small risk however, so it you want to put it on the unit follow Tom's advices for root folder .System or better still Map root folder.

Am I also to copy the JVC file along with gmapsupp.img file?
JCV file goes in JCV sub-folder of .System on unit, or in JCV sub-folder in Garmin folder on card.
Before you ask anymore basic questions, please do the reading suggested by Tom. You'll save time that way for sure.
