Dogshit. Get Uniden R3 at the very least. Better if you get R4

Micro is the common older one, the R3 uses mini USB which sucks. [For the low price of $6.99](https://a.co/d/iYhpavp), you too can update your R3.

"Cobra 700i" = No I say this respectfully: Return that Cobra; it's garbage. Uniden R4 $289 Sams Club. If you're on a budget, you may get lucky with a Uniden R3 under $200 on the second-hand market.
