Garmin 18x PC GPS Navigator Unit

Used this to provide GPS data to Bearcat 996 scanner. Works great, just make sure baud rate set correctly. Outside, captures gps location quickly. Does work inside but a bit slow due to no clear view of sky (not GPS fault, just location). Good value for price.

Bought this for our truck's APRS ham radio. Selected this model for ease of connection, wired a db9 plug to a 1/8" stereo plug and connected the GPS 18PC to the Kenwood TM-D710a radio. Turned on GPS fx in radio and bingo! GPS icon started flashing in corner of radio's faceplate and we're sending packets with our location data. We decided to try it on the dash instead of rooftop for two reasons. The cable was just a little short to extend out to the roof and provide me the inside routing I wanted. And, our Garmin Nuvi has always worked from the dash without any problems. Sure enough, the GPS 18 PC has worked perfectly for two weeks sending location info to our ham radio. We dissected the cigarette lighter plug and removed the spring and button, replaced them with a pair of wires to an Andersen power-pole connector. This maintains the 5.7 volts to the gps 18, and allows us to plug into the switched accessory supply we added to the truck. This Garmin gps looks nice, does everything it's supposed to. No surprises, no problems, works perfectly for the job. [...]

Bought this for my Yaesu 991A for GPS. Too easy to setup and install. No issues, just make sure your baud rate is set to the correct one for Garmin GPS which is 4800. Once that is set you are good to go. 73

I bought this unit over the Uniden brand simply due to name so I can only say how well this one works, which is very well. We went driving for about 5-6 hours yesterday crossing several counties in Texas and it never skipped a beat. I just tossed it on the dash, ran the wires as cleanly as I could, plugged it it and it synced nearly instantly, without any issues, and never lost signal. I took off a star becaure it so darn bulky. One would think in this modern world there could be a better design, minimalizing the product so it's not such an eyesore.

It is compact, does not take much power, locks on quickly and gives good bread crumbs. I have been evaluating this unit as a replacement GPS for my current APRS beacon in my truck (KB5TSI-5) and it is performing admirably. My only complaint is that the cable is too short to run the puck to where I want to mount it. I will be adding a serial extension to the DB9 and I will have to replace this cigarette lighter plug with an Anderson Power Pole to match up with my system. But in all other respects I am quite pleased. Being an emergency management volunteer, we make extensive use of our APRS beacons and having a dependable, low power consumption GPS that will self start when power is applied makes that work much better than the marine GPS I have previously used.

Bought because it was recommended for Yaesu FT991A GPS. Did not work. However it will probably work well in the Garmin world.

Great interface. Connected immediately with my incident home patrol scanner. Just had to get a gender changer.

This is a great unit. Not many GPS receivers still come with a serial port, most have converted to USB. I needed a GPS receiver that would connect directly to a serial port and the Garmin unit was the best value for the price. It typically locks up on a satellite fix in 30 seconds or less from a cold start. I am using the receiver in my vehicle and it tracks perfectly, even in metro areas with building obstructions. I would definitely recommend the Garmin receiver to anyone who needs an inexpensive GPS solution with serial port connectivity.

付属のケーブルで簡単に接続できました。 FT-991AMで外付けGPSが欲しくなったため、社外品で購入。 電源を取る為に安定化電源に付属のシガーソケットを接続。 データーのやりとりをする為、付属の通信ケーブルを接続。 設定は特に必要ありません。 説明書は入っておりませんが繋ぐだけで使えました。

Yaesu AIS に接続してNMEA プロトコルで使用できました。DSUB 9pin のアサインも問題ありませんでした。

FT991の外部GPSとしてモービルで使う為に購入しました。全てwin10(64bit)での使用メソッドです。結論から言えばd-sub 9pinコネクタ（メス）は変換もいらず、ボーレートの変更もせずに一発OKでした。ただし、マニュアルも何も入っていませんでした。 baud rateはデフォルトで4800bpsです。FT991のメニュー[029 232C RATE]もデフォルト4800bps ([028 GPS/232C SELECT]はGPS1 or 2ご希望のものを)なので上手く動作したのでしょう。私はファームウェアのアップデートの際に変更するのが面倒なのでデフォルトのまま使っています。ボーレートの変更をしたい方は、ユーティリティーをPCで動作させ、USB接続（usb to serial変換ケーブルを使用します）が必要となります。いつリンク切れになるか分かりませんが、URLはhttps://www8.garmin.com/support/download_details.jsp?id=4053#Instructです。ここからダウンロードして使います（ソフト名は[SNSRXCFG] software version 3.30）。 使い方は次の通りです。 1) commメニューからPCのcomポート番号を選ぶ（ボーレートはautoのままにしておくとセンサのレートを後で確認することができます）。 2) connectアイコンを押すと、GPSのボーレートを検索・表示し、PCと接続される。 3) configメニューからsensor configurationを選んでボーレートのみを変更する。 4) send config to GPSアイコンを押す。 5) disconnectアイコンを押す。 6) GPSの電源を落として入れる（シガーライタープラグを抜き差しする）。これ重要。 これらの手順で使えるようになります。後は色々とトライしてみてくださいね。 もしかするとリージョンコードではねられる可能性もあるので、とにかくトライです。
