Hi Downhilldai its a bit more than i wanted to pay i dont need one as i have a 178c fitted but just liked the look of a 188c bit bigger screen thats all might sell what i have and have a look round tightlines Alain
You'll have a sounder feature on the 178C which the 192C doesn't have, although can be added via a sounder module. Probably best you stick with what you've got.
