S&M Electro-Tech, Inc
 

Just wondering if anyone used this company for a radio conversion.........www.turnswitch.com. They are out of Blaine, MN

They have been around for years. If the same guy owns it , he was the first guy to make an after market scanner for computer controlled cars. Very smart guy and real nice too.

I've used his conversions for am to am/fm 4 channel stereo with an ipod hook-up. Always excellent, great sound, Greg is a good guy, and the results are worth the $$.
