APK locus pro

[papab]

I have Locus Map Pro on my phones and I'd like to install it on a hammerhead karoo 2.   Where can I find the APK for this?    Do I need to pay another subscription fee?
Thanks for a great app.  I've tried many the Karoo app, and many others, & Locus is the best.

Hi,
all latest stable app versions should be available here: http://bit.ly/lmVersions

Thanks.  I tried running 3.54 (which is what I'm running on my phone), and 3.55.  It goes to Initializing, and 'Process unsuccessful, e, code 1811'.   Any ideas?

Update,  I successfully install 4.4.1

Pro version requires Google Play installed on the device to verify the license. If Google Play is not available, it cannot be started. Maybe this is a problem with your device?
