A year of the lease as listed, plus the install cost and any set-up fee, make up the 12-month column. If a company posts no install price, MADD's typical range (marked *) fills the gap, and the cell says so when no price at all is posted. Quoted by phone: call the company and it gives its price. A guide from MADD's general estimate: the install runs $70 to $150 and monthly fees $60 to $80, roughly $790 to $1,110 across 12 months ($720 to $960 where installs are free).
