I have been researching GPS tracking devices for my car and have just about given up.
- Basically, all require a monthly subscription, $10 to $20 per month
- Clear view of the sky required for stable tracking (Mounting under dash or under trunk/hood not recommended).
- Spot Trace
https://www.findmespot.com/en-us/products-services/spot-trace seems to be the best of the bunch, but still reviews are hit/miss
- All can be easily defeated with a very cheap device plugged into cigarette lighter (search Ebay "GPS Signal Anti Interference Tracking Blocker"
I would be totally OK with the Spot Trace, and $10 per month if it could be mounted discreetly and wasn't so easily defeated.
