I am no scientist; to the contrary. More like a "knobtwister" which is the title my good friends in the 2ndMob gave me. Not being a scientist means I don't take notes. That always becomes a problem as I have to re-learn what I already taught myself. Here's the deal here:
After reading the last several posts, I went to "experiment" on the Nuvi 1300 I have. I fully expected CX 2013.10 to be working. It was not. shock. one thing after another I tried (except unlocking the regular way: I did try to unlock (and in fact thought I had) using the Fast IMG unlocker 2.1 given that, *I think* it was what I tried the very first time. What?! No city streets in Chicago or transit and no EPM? Where'd they go? Tried one thing after another. Got it to work in this fashion:
Stored on the main drive of the Nuvi is the 2013.20 for the lower 49. On the 4 gig sd card I have CX for Amsterdam; an unlock file with .unl as file extension; Navsat 6.4 (Costa Rica); FullCXNA 2014.10; and Benelux 2014.20 (soon to be .30). The best I can figure is the problem started when I disabled the CX map for Amsterdam by re-naming it Amsterdam.img.old and renamed the unlock file to Amsterdam.unl.old . I also renamed Benelux with a .old file extension.
When I renamed the Amsterdam CX map to the .img extension and also the Benelux map to the .img file extension, and also the .unl for the city map of Amsterdam back to .unl, public transport (EPM) came back and so did my walking routes (and public transit routes) within Chicago and I expect all the other cities on the larger map offered.
I shall leave it to the scientists to figure out why it works this way, but working it is.....
EDIT: Perhaps "things" "work" because I already have an unlock file on the SD card for the CX Amsterdam map? I have just created an unlock file for the USA CX map and redacted the "old" Amsterdam unlock file to .bak file extension. The ONE unlock file works for both maps. Is this action common? (Oh...yes...capn....I am using the unit in simulated mode and NEITHER the CN map for the USA or the Benelux map are checked....only the two CX maps are checked.).
@capn: Question: I get a walking route which can include busses on the Nuvi 1300: I get no "EL" or METRA stops; just busses. (In fact when my starting point was the Wilmette, IL Linden CTA station I was only permitted to take the Purple line "EL" into the city and then had to bus it to Midway Airport. The correct route is Linden Purple Express to the City and then Orange line (EL) all the way to Midway....no busses. Are you getting "EL" and METRA stops?
Further, you ask "Are you running "the full CX 2014.10 with the CN 2014.20 with only the one you're using selected"? Or have you found another working combination? I need to UNCHECK the CN2014.20 for EPM to work on the Chicago map.
However, I'm confused because the "full" CX map of USA does not require an unlock "key" (file)....or does it?
Yet another edit add due to "experiment". The CX full (NA) file will not work with my Nuvi 1300 unless I have an unlock "key"/file in there. Doesn't matter whether it's the A'dam key or one freshly made for the CX full (NA). I had read the entire thread before I began posting and I did read all of post 8. There are a couple of what appear to be contradictions within this thread or I'm just too tired to make the distinctions. Too, I had the read the instructions on unlocking. I'm confused beyond a reasonable doubt at this time given post 27 is directing no unlock file is needed?
