These units were in the Cessna 180 when I purchased it. Both worked with no issues when removed for the panel upgrade. New they are over $3,000 each and Bennett Avionics will sell you used for $1995 and $2395 respectively.

I want them gone off my shelf. I am not an avionics shop but I'll give this guarantee. You buy one or both, hook them up and if they are not satisfactory, you can ship them back within 30 days of receipt for a full refund less shipping cost.

170B $1200
170C $1500

Take both for $2500.
