Garmin 010-01539-01 DriveSmart 50LMT GPS Navigator $85.00 refurbished

It says it has voice instructions
But I have bad hearing

How LOUD does the volume adjust to? I'll try and give an example.

With all windows open on a busy city boulevard
Could a "normal" person understand the commands?

That being said it is supposed to have an earphone jack. Does something like a 12 volt powered amplified speaker exist that could plug into the jack?

With my budget eighty five dollars is a chancy roll of the dice.

Thank you

I wear hearing aids and the Garmin Nuvi 2856 is loud enough to hear over the Cummins in our 2001 Dodge. However it doesn't have an earphone jack. Some of the newer ones don't have one, so you might double check to make sure the one you're looking at has the earphone plug.

I have a Magellan and it's a nicer unit. Same price and has a dash cam too and...I can hear it just fine.
