Just D3084130A.JCV file contains much less junction views than the file D2504160A.JCV.

How are not bored to discuss about it from version to version???
No difference in picture (JCV image). D2504XXXA.JCV was smaller for placement into 4Gb memory of LMT device. Less JCV image is less size in Gb. Now in any case we need SD for whole coverage but Garmin is very conservative and marketing subordinate company. Maybe in body of JCV image present any difference but I catch only difference in lack of some JCV in small files for all gone years.

Because the terms 'Resolution' and 'Picture Size' do get constantly confused and although interrelated to some degree [Picture Size determines total pixels so affects Resolution] clearly Resolution is comparative and can only be either High or Low when comparing one image to another, or the one image to itself on different size screens, i.e. more or less ppi means higher or lower resolution.

I honestly don't think it's really worth comment in any case because the inference caused by the incorrect interchangeablity of the two terms is so widespread as to make it almost acceptable. Confusing Resolution with overall file size however is not acceptable although it sometime happens. In this case as Caty points out to me in a Visitor Message, she believes that monterra simply means that the two files are for different models with which opinion i agree. However if one file is labeled 'High Resolution' it must be higher compared to something else, hence the possible implication the first is higher res. than the second.

Best we roll with it imo, and simply accept the quirky usage just as we accept VendorID.

Neil, I hope you had the well thought than quoted me.
I remember what Nuvi 1xxx had LaneAssist upto nuvi13xxand14xxseries_regionfileonly__490.gcd. After Garmin hammered a nail in attempt to pack the map and additional files into 4GB of internal memory the nuvi13xxand14xxseries_regionfileonly__500.gcd gave me new from MapUpdater a file with new identifier - LaneAssistFull. But for Nuvi 765 it stayed the same - LaneAssist. I was younger than old maid age limit and made classic test with two navis (765 and 1390) on windscreen. Only one difference was noticed it was less number of JCV pictures on route. On back route I put LaneAssistFull in 765 and score became equal. After this I remember about LaneAssist (smaller by size) file if I do not have sufficient place in memory for any devices only.
Now I am legal old maid and de jure I do not must have good brains in my head. It is easier for me to write off this fact to Garmin marketing quirks. I think that only syzygy can analyze both file and make an objective judgment.

1. D2504160A.JCV has JCV pictures for 10 more tiles than D3084130A.JCV. See post #11.
2. Within a common tile, D2504160A.JCV has pitcures for more junctions than D3084130A.JCV.

I was speaking about it 3 year ago yet. But...
So I think you must blog your post because after 2015.10 would be released this question be in heat again.

Beta version of ImgTool can analyze it too and it is the greatest tool and be especially waiting for release!!! But if somebody could share this beta with me it would be advisable. I am not fan to annoy in PM...
