Thread: Enable features in your nuvi 12xx, 13xx and 14xx - JCV, LA, TTS

It's fine not to include a quote when you're doing a following post, in fact it's better that way for the very reason you've stated.

Ok, you've got one of the Mediatek [MTK] chip 1300s, rare in AU. 620 is just the software [firmware] version, i.e. version 6.20 which is the latest. My pack for 0972 would simply be ignored by your MTK unit, the same as it will ignore the 3 other folders in Acleite's pack supplied by dasilvarsa and would only flash from the contents of the folder named 1104.

All garmin units have a section of the flash which is not user accessible. It's divided into 'regions' [rgn] numbered 1 to 255, but nowhere all are used. Region 16 contains the logo splash, that's what gets replaced with the 'senior' models rgn16 [16.bin in the Garmin folder] to enable the extra features. Region 41 is encrypted and contains vital and unit-specific info, including unlock codes. In the event that a unit gets badly bricked and is not recoverable any other way, it may be possible to fix it by restoring rgn41 from a backup [41.bin].

When you get this working DON'T have more than one JCV file and only in one location. So DON'T have them both, or one duplicated on both the unit and microSD. Choose one or the other but never both. I'd get rid of the smaller one. You must make sure that you always have the right one for a new map and get rid of any older version map's jcv files too.

For the flash, you can do a 41 backup using the guide in that thread and then flash with the universal pack. Or you can flash with this pack specifically only for 1104 MTK units with the rgn41 backup included:

Thx enormously Neil - you are a WIZARD. Everything now working on Simulation - keen to try it out for REAL tomorrow am. LA works, JCV works, and SLI works too. You guys are amazing.

Now just one last point for revisiting - Bluetooth. My daughters 1390 has it but I didn't think to ask in 2011 when I purchased this 1300 - and I have no BT system in my 2007 Honda Accord. Do you or anyone else know (or have stripped the unit down to see?) if the PCB has either a BT chip on it (and not active) or has an empty socket for a BT chip. If it needs a chip pressed it I would like to try to source it and install for BT function. Considering how similar the 13XX were I would think that the PCB are all the same and just different features activated depending on the Model and maybe needs one of those other [Regn] you talk about.

I realise this might be slightly OT but it IS a feature (albeit HW) of the 13xx that I would hope to activate???
Any ideas?
Thx again

PS the Basemap link you provided about 4 posts ago to a share server does NOT work. Could you supply another link? Thx. PG

Yep, if you want to continue it open a thread in [Only registered and activated users can see links. ]. Or if you prefer just send me a Private Message and i'll move/copy and edit the existing posts here to a new thread for you.

PS: This is fully OT, but whenever i have connected any BT device to my phone i've been given the choice to 'connect automatically'. In my Nokia phones it could also be changed later under Bluetooth>Paired Devices>Options>Set as [un]authorised. If you have a Nokia PM me and i can help you with that.

EDIT: Some posts copied to a discussion thread created here: [Only registered and activated users can see links. ] and edited accordingly. All OT posts then moved to [Only registered and activated users can see links. ].

@lqzurich
G'day. Interesting question, probably even TTS can be enabled on 1100. It runs the same fw as 1250 and afaik they're identical hardware but like with some 12x0/13x0/14x0 many features are blocked by it's region 16 [logo splash]. TTS, SLI, LA, JCV are all blocked on 1100.

I'd like to know what splash version is presently on your unit. Press and hold battery symbol for ~6 seconds, press 'Next'>'Start Test'>'More' and look for 'Splash'. My Canadian 1200 and US 1300 both originally had splash of D1340-00.

I've not updated an 1100, but by flashing the logo either using Lolypop000's pack for 1200 HWID 0971, or acleite's generic microSD method [both in initial post], all of those features including TTS should be enabled. Your unit will still identify as a nuvi 1100 on start-up but if successful it will function like a 1250.

Your report would be welcome.

I am almost completely sure TTS will be enabled. D1340-09 probably disables TTS as well as everything disabled by D1340-00. 2.00 is just the logo version, it's immaterial. Please take a back up of your rgn16. If you use the microSD card method, it will do the backup for you. Then if there's any problem rgn16 can be restored from the backup, but it's unlikely to be needed.
